Clarification on Brain MRI Findings
Hello, I recently underwent a brain MRI and I am seeking some clarity regarding the results. I am a 26-year-old woman, and I've been diagnosed with Hashimoto's disease since 2018. In 2021, I began experiencing migraines, vertigo, along with a persistent stiffness in my neck and shoulders. Additionally, I have noticed a lump at the base of my skull during this time. After ruling out any cardiac issues through various tests and confirming that my blood work is normal, I opted for the MRI to exclude the presence of tumors. Fortunately, no tumors were detected, but the scan did reveal a few cysts. Here’s where I’m confused: the report mentions a Thornwaldt cyst; however, from what little information I've found—since this condition is quite uncommon—it appears to be located in the nasal cavity. Yet, my MRI suggests that it is related to the bump at the back of my head. Is this discrepancy possible? Could there be an error in the interpretation of my results? The lump I’m concerned about is situated on the left side at the base of my skull, quite close to where the occipital nerves would typically be situated. Is it feasible for the cyst to have moved to this area, or might the MRI diagnosis be inaccurate? I appreciate any assistance in helping me understand this situation better.

It’s understandable to feel concerned about the findings of your brain MRI, especially given your symptoms and medical history. I’ll clarify the information regarding the Thornwaldt cyst and its implications for your situation.
Key Points
- Thornwaldt Cyst Location: Thornwaldt cysts are usually located in the nasopharynx (the area behind the nose) and are often asymptomatic. They can sometimes be detected incidentally on imaging.
- Lump at the Base of the Skull: The lump you’re feeling at the base of your skull may not be directly related to the Thornwaldt cyst. It’s possible that the MRI findings mentioned could describe two separate issues.
Explanation
- Cyst Details: Thornwaldt cysts can appear on MRI, but they generally wouldn't cause a lump on the neck or base of the skull. The lump you described could arise from several causes, including muscular tension, benign bone growths, or even lymph nodes reacting to inflammation.
- Interpreting the MRI: It’s essential to remember that imaging can be complex, and subtle variations may need clarification. While it’s uncommon for a Thornwaldt cyst to cause noticeable symptoms, it is unlikely for it to present as a lump in that area.
Next Steps
- Document Symptoms: Keep a detailed record of your symptoms (such as pain, stiffness, or changes in the lump) to share with your healthcare provider.
- Follow-up Appointment: Request a follow-up consultation with your doctor or neurologist to discuss the MRI results in detail. Ask for clarification specifically about the Thornwaldt cyst and the lump.
- Consider Imaging Review: If you still have concerns about the accuracy of the MRI interpretation, discuss the possibility of having the scans reviewed by another radiologist for a second opinion.
- Evaluate Symptoms: Monitor the lump for any changes in size, shape, or associated pain. If you notice any rapid changes, that would warrant more urgent evaluation.
Your symptoms and concerns are valid, and seeking clarity is a critical step toward understanding your health. Please don’t hesitate to reach out for more information as you navigate this process.

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.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
