Closure of Anterior Fontanelle: Seeking Guidance
Hello everyone, I could really use some support, and I’m curious to know if anyone else has experienced something similar or has insights into the findings we've encountered. I reside in North Carolina, and my baby was born on April 30th of this year. Just two months after his birth, I discovered that his soft spot had disappeared. Strangely, this change went unnoticed by the doctors, including one during our initial visit after switching physicians, who also failed to examine his head thoroughly. We were referred to a neurologist, who confirmed that she could not detect the soft spot either, though she reassured us that my little one seems to be developing well. During the examination, she performed a typical check, shining a light into his eyes to see if he followed it. One concern we noted was his excessive crying throughout the day, which has improved slightly (we believe it may be related to his formula, and we are addressing it). She recommended a CT scan, which we completed. As of today, my baby has reached the age of 3 months, and I received the results last night, but they only included descriptions without any imaging. I’m seeking clarity on the findings, especially since the neurologist considered the possibility of Craniosynostosis. However, the results referenced a different medical code. The initial visit summary mentioned "small anterior fontanelle closure,” which leaves me puzzled—does this indicate a mere possibility or is it definitive? Moreover, the results indicate that the fontanelles have closed, but the suture lines remain visible. We have a follow-up appointment scheduled for August 5th. Fortunately, there is currently no abnormal head shape observed. He truly is our precious boy. Does this situation imply that we should closely monitor his head growth, given that the sutures are still open? I have concerns about how to recognize if they close as he grows and the potential stress of it possibly becoming problematic, or whether my baby might experience pain in the future. We’ve been told that if Craniosynostosis were the case, addressing it surgically now would be preferable to dealing with it later in life. Alternatively, could it be that the closure we see indicates the potential need for surgical intervention? **INDICATION:** Small anterior fontanelle closure; congenital malformation of skull and facial bones, unspecified (Q75.9). **COMPARISON:** None. **TECHNIQUE:** Axial CT images of the brain were obtained, covering the skull base to the vertex, including parts of the face and sinuses, without contrast. Additional 2D reformatted images were produced and reviewed as necessary. **FINDINGS:** - **Calvarium/Skull Base:** No signs of acute fractures or destructive lesions observed. The mastoids and middle ears show no significant mucosal disease. Both anterior and posterior fontanelles are closed, although the suture lines remain visible. - **Paranasal Sinuses:** No air-fluid levels detected. - **Brain:** No significant vascular territory infarcts. No mass effects or hydrocephalus detected. There is no evidence of acute hemorrhage. **IMPRESSIONS:** Anteior and posterior fontanelles have closed, but the suture lines are still visible at this moment. **AGE:** 3 months. **SEX:** Male. **HEIGHT:** 25.4 inches. **WEIGHT:** 13.4 pounds. **RACE:** White. **DURATION OF COMPLAINT:** Unsure. **LOCATION:** North Carolina. **PRE-EXISTING RELEVANT MEDICAL ISSUES:** None. **CURRENT MEDICATIONS:** None.

It's completely understandable to feel anxious about the closure of your baby's anterior fontanelle and the related findings. Let’s break down what you've shared and focus on the key points to alleviate your concerns.
Main Points:
- Your baby’s soft spot (fontanelle) has closed earlier than typical for his age.
- Although there are visible suture lines, no immediate concerns were noted by the neurologist.
- A follow-up appointment is planned, allowing further evaluation and reassurance.
Explanation: The anterior fontanelle usually closes between 9 to 18 months, so closure at 3 months is earlier than average. However, if the suture lines remain visible, this typically suggests that while the fontanelle has closed, the skull can still expand normally as your baby grows. This is usually not a cause for alarm as long as his head shape appears normal and there are no other concerning symptoms.
Craniosynostosis is a condition where one or more of the cranial sutures close prematurely, which can affect head shape and brain development. The absence of abnormal head shape, along with the normal findings on the CT scan — such as no signs of acute fractures, hydrocephalus, or brain abnormalities — suggests that immediate aggressive intervention may not be necessary.
Next Steps:
- Monitor Growth: Keep track of your baby’s head circumference as part of regular pediatric check-ups. Your pediatrician can help you measure this and assess growth patterns over time.
- Attend Follow-Up Appointments: Utilize your upcoming appointment on August 5th to discuss the CT results in detail. Ask the neurologist about the implications of the fontanelle closure and what to watch for as your baby grows.
- Observe for Signs: Be attentive to any signs of increasing head circumference, vomiting, excessive crying that seems different, or developmental changes, and report these during your next visit.
- Discuss Concerns Openly: When you meet with the neurologist, communicate all your concerns and ask specifically about the potential need for surgical intervention. Understanding options, timelines, and symptoms to watch for can help ease anxiety.
You’re dedicated to your baby’s health and well-being, and that’s commendable. Monitoring and communicating effectively with your healthcare team will ensure you’re addressing any concerns appropriately. Let me know if you have any more questions or need further clarity on this topic!

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
