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.
