Concerns Over Microcephaly Diagnosis While Awaiting MRI Results
I’m a 25-year-old woman, 5’4” tall, weighing 180 lbs, and currently 26 weeks into my pregnancy. Recently, I've been feeling anxious about my baby's health. I've attached some images of my ultrasound results and reports, along with a profile photo of my boyfriend and me. Is it feasible that my baby's head size is simply smaller? My boyfriend does have a slightly slanted head, and I noticed that previous ultrasounds marked the profile as normal; it makes me question their accuracy. Throughout my pregnancy, my little one has remained in the same position since the 20-week scan, tucked right against my pelvis and facing my back. It’s incredibly distressing to feel her move so much at times. I’ve heard numerous accounts from mothers whose children were initially diagnosed with small head sizes but came out perfectly healthy. However, I recognize that an accurate diagnosis requires more than just ultrasound impressions, and the MRI we are waiting for will determine whether her brain development is typical. I visited my maternal-fetal medicine (MFM) specialist two days ago, and the experience felt more like a whirlwind. Reviewing my earlier ultrasound reports suggests that my baby’s head was at the 3rd percentile during the 20-week assessment, though this concern was never communicated to me. The doctors mentioned her positioning hindered a full anatomy scan, advising a follow-up in four weeks. Fast forward to my latest visit, her head circumference had unfortunately dropped to below the 1st percentile, alongside other metrics like the biparietal diameter (BPD) also falling under 1%. Meanwhile, her weight decreased from the 32nd percentile to the 12th. My regular OB had initially downplayed the concerns and referred me to MFM for a final anatomy scan. Afterward, I seemed to leave the office believing everything was fine until the doctor mentioned microcephaly. Now, her head measurements and BPD are consistently under 1%, and her weight is now at 16%. Additionally, they indicated that her forehead appears sloped, marking her development at -3 to -4 standard deviations from the norm. I spoke with a genetic counselor, and they took blood samples from both my fiancé and me. We also managed to complete an amniocentesis on the same day and are now waiting to hear back regarding scheduling the MRI. They mentioned little other than the fact that microcephaly could lead to developmental setbacks or seizures, and that there’s a possibility she may not walk or talk in the future. It’s excruciating to consider how far along I am and that results won’t arrive for about three weeks. By the time we have answers, I’ll be nearing 30 weeks pregnant. They provided minimal information about the MRI's purpose, and my next growth scan isn’t scheduled for another month. I can only assume the MRI will check if her brain development is on track, although the current report indicates that everything appears normal apart from the CSP region being described as 'sub-optimally visualized.' The stress has reached a level where it’s affecting my physical health, making it hard to eat and even causing vomiting—attributes I know are unhealthy, especially while carrying my baby girl. So far, tests for infections like Toxoplasmosis and CMV have come back negative. However, I still face a two-week wait before receiving genetic testing results.

I'm truly sorry to hear about the concerns you're experiencing regarding your baby's health. It's completely understandable to feel anxious given the information you've shared. Let's break this down and focus on what you can do during this waiting period.
Main Points
You are dealing with uncertainties related to your baby's head size, and you have several upcoming tests to help clarify the situation. It's important to prioritize your wellbeing as well as your baby's while awaiting further information.
Explanation
Microcephaly refers to a smaller-than-average head size, which can be associated with a range of developmental issues, but it’s crucial to remember that not all cases lead to serious problems. It's also common for head sizes to vary due to genetic factors, including parental traits. Your baby’s position and the difficulties in obtaining measurements during ultrasounds can add to the uncertainty, but this doesn’t necessarily indicate a problem.
As you've mentioned, the MRI is essential to evaluate your baby's brain development further. It’s normal to feel anxious waiting for results, especially when it involves your child's health. Ensuring both you and your baby are healthy is paramount at this time.
Next Steps
-
Focus on Self-Care:
- Hydration and Nutrition: Try to stay hydrated and eat small, nutritious meals. If you’re having trouble with nausea, consider bland foods like crackers and ginger tea, which can be easier to tolerate.
- Stress Management: Engage in relaxation techniques, such as deep breathing exercises, meditation, or gentle prenatal yoga if allowed. This can help reduce anxiety and improve your physical health.
-
Engage with Support:
- Talk to Someone: Share your feelings with a trusted friend, family member, or even a support group for expectant parents facing similar concerns. Knowing you’re not alone can help alleviate some stress.

Concerns About Microcephaly: Awaiting MRI Results
I am 25 years old, standing at 5’4” and weighing 180 pounds, currently at 26 weeks into my pregnancy. Feeling overwhelmed, I’m anxiously counting down to an MRI that won’t happen for another two weeks. I've been trying to make sense of all the ultrasound images and reports that show my partner and I's facial profiles alongside the baby’s development. Could it simply be that her head is just small? My partner has a noticeably slanted head shape, and the previous ultrasounds labeled our baby’s profile as normal, which makes me question whether that assessment was accurate. Since her 20-week scan, she has remained in the same position, curled up in my pelvis and facing my back; despite that, she moves around a lot, which is both comforting and disheartening. I’ve stumbled upon numerous accounts from parents who were informed that their babies’ head sizes were below average, only to later find out that everything turned out alright. I understand that a conclusive diagnosis can't be made from the ultrasounds alone; the MRI will help determine whether her brain's development is within the normal range. I had a consultation with my Maternal-Fetal Medicine (MFM) specialist two days ago, and it all felt like a blur. Reflecting on my past ultrasound reports, it appeared her head was in the 3rd percentile at the 20-week scan, which was never mentioned to me. The medical team indicated that her positioning made it challenging to complete the anatomy scan, suggesting I return in four weeks. Upon my return, the measurements revealed her head circumference had dropped below the 1st percentile, and likewise for the biparietal diameter (BPD), which also fell below 1%. Her weight had decreased from the 32nd percentile to the 12th percentile. My regular obstetrician expressed that there was nothing alarming and referred me solely to MFM to finalize the anatomy scan. After the scan, I was initially reassured until the doctor mentioned the term microcephaly—now her head, BPD, and several other related measurements are all below the 1st percentile. Her weight is currently at the 16th percentile, and it was also noted that her forehead has a sloped appearance. The measurements indicated she is 3 to 4 standard deviations below the normal range. A genetic counselor met with me, and samples from both my fiancé and I were collected for testing. They performed an amniocentesis on the same day, and now I'm waiting to hear back from them regarding the MRI scheduling. I feel like I wasn’t given sufficient information other than the fact that microcephaly can lead to potential developmental delays, seizures, and possibly lifelong difficulties with walking and talking. The uncertainty is frightening, especially with the results not expected for about three weeks following the amniocentesis. By then, I will be around 30 weeks along. The purpose of the MRI remains unclear, and I am not scheduled to have another growth scan for a month. I assume the MRI is meant to assess whether her brain is developing normally, yet thus far, everything appears to be typical except for the mention of the CSP (cavum septum pellucidum) being described as "sub-optimally visualized," whatever that means. The worry is consuming me to the point of losing my appetite and experiencing nausea, which I know is unhealthy for me and my baby girl. Fortunately, tests for infectious diseases such as Toxoplasmosis and CMV have come back negative. However, I still have two weeks to wait for the results from the genetic testing.
Seeking Help for Recurring Pinworm Infection
At the age of 28, I encountered pinworms for the very first time last year while working as a teacher. Although I successfully treated the infection, the experience left me emotionally drained, particularly because I have a diagnosis of OCD. My anxiety about potential reinfection was so severe that I ultimately decided to leave my job, prioritizing my mental health and well-being over my career. During my treatment, I took albendazole numerous times, far too many to remember, and was meticulous about maintaining hygiene in my daily life. Fortunately, my efforts paid off, and I believed the problem was resolved. However, remarkably, exactly one year later, I started feeling that unmistakable, unsettling itch around my anal area—a reminder of my previous ordeal. Panic set in immediately. Rushing to the restroom, I was horrified to discover the pinworms present in my stool. Despite my vigilance since my last infection, with regular checks on my stool, it had been an entire year without any signs, and I hadn’t experienced any itching until now. Could it be possible that I contracted the pinworms from a new source, or is it conceivable that they were lurking in my body unnoticed for a year? I took every precaution; I insisted that my family, boyfriend, and friends all take the medication as well, adhering strictly to the treatment regimen. Moreover, I was so careful with hygiene that I discarded my clothing and bed linens daily and meticulously disinfected every surface in my home. My fear is consuming me, and the trauma of this repeated experience is overwhelming. I desperately need reassurance that I haven't been harboring these worms for a year and that I can effectively eliminate them. This stress is affecting my upcoming wedding and my postgraduate studies, pushing me to the brink of despair. Will this ever come to an end?
Concern Over Potential Microcephaly Diagnosis: Waiting for MRI Results
Age 25, Female, standing at 5'4" and weighing 180 pounds, currently at 26 weeks of pregnancy. I've shared images of my ultrasounds along with some reports and a profile picture of both my partner and myself. Could it be that my baby's head is simply smaller than average? My boyfriend has a naturally slanted skull, and during previous ultrasounds, my baby's facial profile was noted to be normal, though now I find myself questioning that assessment. Since my 20-week ultrasound, she has remained in the same position, curled up against my pelvis with her back facing me. Her movements are constant and quite emotional for me to witness. I've come across numerous accounts of parents who were initially told their babies had smaller head measurements, only to later have healthy children. I realize that a proper diagnosis cannot be solely based on these measures, as we will need the MRI to assess the condition of her brain. My Maternal-Fetal Medicine (MFM) appointment two days ago was overwhelming. Looking back at the ultrasound reports, I noticed that at 20 weeks, her head size was at the 3rd percentile, but this wasn't communicated to me at the time. The physicians noted that her position rendered it difficult to complete the anatomy scan, advising me to return in 4 weeks. However, upon my return, her head circumference had fallen to below the 1st percentile, along with the BPD also measuring under 1%. Additionally, her estimated weight decreased from the 32nd to the 12th percentile. My primary care OB reassured me that there was nothing to worry about and merely referred me to MFM to complete the anatomy scan. I initially felt optimistic after the scan, but then the doctor mentioned the term microcephaly, indicating that her head size and other measurements had all dropped to below the 1st percentile. Furthermore, her weight is now at the 16th percentile, and they noted a sloped forehead as a concern. They confirmed that she is measuring between -3 and -4 standard deviations from the norm. After discussing with the genetic counselor, my fiancé and I had our blood drawn. They performed the amniocentesis on the same day, and I am now waiting for a call to set a date for the MRI. Unfortunately, they did not provide much information, only mentioning that microcephaly could lead to developmental challenges, risk of seizures, and potential difficulties with walking or speaking. The anxiety of waiting for results is excruciating, especially as I approach 30 weeks, and the results from the amniocentesis won’t be available for another three weeks. Additionally, my next growth scan is not scheduled for another month. I assume that the MRI is meant to check the brain's condition, yet thus far, everything appears to be normal with the exception of a note indicating "sub-optimally visualized" regarding the CSP, whatever that implies. This situation has caused me so much distress that I find it hard to eat, and I've been experiencing nausea. I understand this is detrimental not only to my own health but also to my baby. Fortunately, tests for infectious diseases like Toxoplasmosis and CMV have come back negative. However, I have to wait an additional two weeks for the genetic test results.
Concerns Over Microcephaly Diagnosis: Navigating Uncertainty
I am a 25-year-old woman, standing 5'4" and weighing 180 pounds, currently 26 weeks into my pregnancy. Recently, I've found myself anxious due to an ongoing situation concerning my baby's health. My boyfriend and I have shared some ultrasound images and reports that highlight our baby’s facial profile, which I would have liked to include here but have opted to leave out. I keep pondering whether it’s possible that my baby’s head is simply smaller than average. My boyfriend has a pretty slanted head shape, so I wonder if that could be a factor affecting the measurements. During my previous ultrasounds, the "profile" was marked as normal, and I find myself questioning the accuracy of those results. The baby has remained in the same position since my 20-week scan, curled against my pelvis and facing my back, and while her movements are frequent and delightful, they also make this worry more profound. I've come across several accounts of parents who were initially informed that their baby had a small head circumference only to later have healthy deliveries. However, I understand that a definitive diagnosis cannot be made based solely on scans; an MRI is necessary to ascertain whether her brain development is typical. During my maternal-fetal medicine (MFM) appointment two days ago, it felt like everything was overwhelming. Upon reviewing my past ultrasound records, I noticed that at 20 weeks, the head measurements were in the 3rd percentile, yet no concerns were communicated to me at that time. The medical staff indicated that the baby’s position hindered a complete anatomy scan, and I was advised to return four weeks later. When I did, the head circumference had dropped below the 1st percentile, and the biparietal diameter (BPD) had similarly fallen to under 1%. In addition, the fetal weight decreased from the 32nd percentile to the 12th. Although my regular OB assured me there was nothing concerning and referred me back to MFM to finalize the anatomy scan, my follow-up with the doctor took a worrying turn. The diagnosis of microcephaly was brought up, indicating that both the head and BPD measurements were now significantly low. Her weight is currently in the 16th percentile, and I've been informed that her forehead appears sloped. Reports suggest she is 3 to 4 standard deviations below the expected norm. After meeting with a genetic counselor, blood samples were taken from both my fiancé and me, and I underwent an amniocentesis the same day. I am awaiting a call to schedule the MRI, but the information shared was quite limited—highlighting that microcephaly can lead to various developmental challenges, seizures, and potentially limit walking or speaking. This is terrifying, especially as I approach the 30-week mark without immediate test results. The purpose of the MRI wasn’t thoroughly explained, and my next growth scan is still a month away. I assume it will clarify whether the brain is functioning within normal parameters, although one finding indicated that the Corpus Callosum was “sub-optimally visualized,” which leaves me with more questions than answers. This entire experience has caused significant distress; my anxiety has escalated to the point where I've lost my appetite and have been feeling nauseated, which I realize is detrimental to my health and that of my baby girl. While infectious disease tests for Toxoplasmosis and CMV came back negative, I have to wait an additional two weeks for genetic results to arrive, which only adds to my worry.
Concerns Over Microcephaly Diagnosis: MRI Delay Causing Anxiety
I’m a 25-year-old woman, standing at 5’4” and weighing 180 lbs, currently in my 26th week of pregnancy. Recently, I've been grappling with worries surrounding my unborn daughter’s well-being, particularly after receiving worrying ultrasound results. Though I've shared images of the ultrasounds and other relevant reports, my concern rests on whether her head size might just be smaller than average, as my boyfriend has a somewhat angled head shape. It was noted in past ultrasounds that everything appeared normal, but now I'm regretting that I didn’t push for clearer explanations. Since around week 20, she has consistently been positioned against my pelvis with her back toward me. Despite her frequent movements causing me much heartache, I’m clinging to stories of other parents whose babies were initially said to have small head sizes but ended up healthy. I understand that an accurate assessment will depend on the upcoming MRI to determine the brain’s condition. A couple of days ago, I attended an appointment with my maternal-fetal medicine specialist (MFM), and it all felt overwhelming. After reviewing the previous ultrasound reports, I saw that at the 20-week check-up, her head size was recorded at just 3%, yet this was never brought to my attention. The doctor reported that her position hindered a complete anatomy scan, and instructions were given to return in four weeks. When I did return, the measurements showed a concerning decline with her head circumference and biparietal diameter (BPD) both dropping below the 1st percentile, while her weight decreased from the 32nd to the 12th percentile. Although my primary OB reassured me at first, referring me to MFM just to complete the scan, the subsequent meeting with the doctor revealed a diagnosis of microcephaly. Now her head measurements are below the 1st percentile, with a 16% weight comparison. I was also informed that her forehead has a noticeable slope, placing her -3 to -4 standard deviations from the norm. I had a session with the genetic counselor, where blood samples from both my fiancé and I were collected, and the amniocentesis was performed on the same day. I’m currently anxiously awaiting a call for scheduling the MRI. Although the prognosis of microcephaly includes possible developmental challenges, seizures, or even limitations in mobility and speech, I find it terrifying to consider being at this stage, especially since results from the amniocentesis are expected in about three weeks—right when I will be 30 weeks along. There was also a vague mention that the MRI is to assess brain health, but clarity on what will actually be evaluated was lacking, compounded by the next growth scan being scheduled a whole month away. At this moment, I’m consumed with anxiety to the extent that my appetite has vanished, leading to bouts of vomiting—something I know is detrimental for my daughter’s health. So far, tests for infectious diseases like Toxoplasmosis and CMV came back negative, but I still have another two-week wait for genetic test results. The weight of uncertainty is incredibly challenging to bear.
