MRI Findings: Benign Meningioma, CSF Flow Challenges, and Chiari Malformation
Greetings everyone, I'm 38 years old and have just received my MRI results. I haven't yet had a chance to consult with my neurologist, and I'm feeling quite anxious, thinking the worst about my health. My understanding is that I've been diagnosed with a benign meningioma located in areas of my brain linked to memory and executive functions—this might explain some struggles I've faced, which made me question if I could be dealing with dementia. Additionally, my MRI reflects issues with CSF (cerebrospinal fluid) flow, which seems reduced or attenuated. The initial reason I sought the MRI was due to symptoms I believe were caused by a Chiari malformation that I've known about since childhood. Lately, I've been experiencing severe brain fog, difficulties with memory, and a feeling of mental cloudiness. I've also been noticing blurry vision, worsening tinnitus whenever I look upwards, and an overwhelming sense of fatigue—I find myself needing about 10 or more hours of sleep at night and an extra 3 to 5 hours during the day. My pressing questions are: • How serious could this condition be? • Is the meningioma or the CSF issue responsible for my symptoms? • Should I consider advocating for surgical options? Any insights or advice would be really appreciated—I'm feeling quite overwhelmed and fearful. I have a devoted husband and a beautiful three-year-old daughter who mean the world to me. **MRI Impression Summary** 1. Mild tonsillar ectopia observed, without signs of cervicomedullary kinking. 2. Biphasic CSF flow noted around the ventral and dorsal aspects of the foramen magnum. 3. An 8 mm enhancing lesion associated with the dura over the left occipital lobe, likely a small meningioma. 4. No evidence of acute infarct detected. **MRI Exam Details** **EXAMINATION:** MRI of the brain with and without contrast. **INDICATION:** History of Chiari malformation; MRI conducted before a neurology appointment. **COMPARISON:** None. **TECHNIQUE:** MRI scans of the brain were taken with and without intravenous contrast. **FINDINGS:** *Brain:* No signs of acute infarction, intraparenchymal bleeding, or abnormal masses. No midline shifts. The cerebellar tonsils are positioned below the foramen magnum, extending up to 7 mm. *Ventricles/Extra-Axial Spaces:* There is an enhancing lesion based in the dura on the left occipital lobe measuring 0.8 x 0.3 cm, displaying mild hyperintensity on T2 sequences. No hydrocephalus or fluid collections were present. CISS images indicate narrowing of the upper cerebral aqueduct with partial effacement of the fourth ventricle. *Intracranial Flow Voids:* Arterial and venous sinus flow appearances are normal. *Cranium/Scalp:* Findings are unremarkable, along with visualized facial structures. *CSF Flow Analysis:* Anterior to the brainstem exhibits biphasic CSF flow at both the anterior and dorsal segments of the foramen magnum. Normal biphasic flow is evident along the cervical spinal cord. However, there is attenuated biphasic CSF flow noted behind the cerebellar tonsils and in the distal ventricular system.

I'm glad you reached out to share your MRI findings and express your concerns. It’s completely normal to feel anxious when facing health uncertainties, especially with the details you’ve shared regarding your brain MRI.
Key Points:
- Benign Meningioma: Your MRI indicates a small meningioma, typically non-cancerous. While symptoms may arise if it impacts surrounding brain tissue, it is often managed effectively.
- CSF Flow Issues: The findings of altered CSF flow and your known Chiari malformation could be influencing your symptoms like brain fog and fatigue.
- Next Steps: Advocacy for surgical options may depend on how symptoms progress and the insights from your neurologist.
Explanation:
Meningiomas are generally benign tumors that can grow slowly. They may exert pressure on nearby areas of the brain but often do not require immediate intervention if they are small and not causing significant symptoms.
CSF Flow Issues: Abnormal CSF flow can lead to pressure changes in the brain, which might explain the brain fog, vision problems, and fatigue you’ve been experiencing. The Chiari malformation can further complicate normal CSF dynamics, leading to additional symptoms.
Actionable Next Steps:
- Keep a Symptom Diary: Document your symptoms over the next week—note when they occur, their severity, and any potential triggers. This will be valuable for your upcoming consultation with the neurologist.
- Hydration and Rest: Ensure you are drinking enough water and maintaining a healthy sleep routine. Adequate hydration and rest can help mitigate fatigue and promote clearer thinking.
- Follow Up with Neurologist: Schedule or prepare for your appointment with the neurologist. Discuss your symptoms, the MRI findings, and express your concerns about surgical options. Advocate for a thorough evaluation of how the meningioma and CSF flow issues might be managed, particularly in relation to quality of life.
- Explore Support Resources: Consider talking with support groups or finding a counselor to help manage anxiety around health concerns. Connecting with others may provide comfort and coping strategies.
Ultimately, while it's understandable to feel overwhelmed, focusing on manageable actions and staying engaged with your healthcare provider will be key in navigating this challenging time. Your health concerns matter, and finding a supportive community can also help ease some of the anxiety. Please don’t hesitate to ask more questions or seek clarification on specific points.

Understanding Pancreatic Cysts at a Young Age
At 23, discovering you have pancreatic cysts can certainly raise concerns, but I assure you I’m not overly anxious. Recently, I had to visit urgent care due to persistent vomiting and severe abdominal discomfort that made eating nearly impossible. A CT scan revealed a cyst located in the head of my pancreas. Following this, my primary care physician recommended an MRI for a more detailed examination. The findings indicated that the cyst resembles a serous cystadenoma, prompting the need for an endoscopic ultrasound (EUS) and a biopsy. I have a consultation scheduled with a gastroenterologist in two weeks to further discuss my condition. Currently, I'm facing challenges with eating; my stomach aches frequently, and I’ve started to lose weight as a result of my limited intake. I’m curious about a common descriptor for these types of cysts — often referred to as "grandmother cysts" due to their prevalence in women aged 60 to 70. However, I’m still quite young in my early to mid-20s. My primary concern isn't the possibility of cancer but rather the implications of having such a cyst at this age. How rare is it to encounter pancreatic cysts during one’s twenties? Additionally, will my age and current symptoms influence the treatment approach that I might receive?
Is There Diagnostic Value in Elevated TNF Alpha Levels?
F24 Currently, I am experiencing a range of symptoms that include: - Widespread muscle twitching, also known as fasciculations, which initially began near my eyes and have since spread throughout my body. - Persistent fatigue, along with pain and weakness, particularly in my legs. - Episodes of night sweats that have lasted for several weeks. - Unintentional weight loss. - A noticeable decline in my immune system, evidenced by three urinary tract infections this month. - A mild feverish sensation and low-grade fevers during the evening hours. - Digestive troubles such as bloating, stomach pain, loss of appetite, and diarrhea. - Muscle aches, joint discomfort, and occasional headaches. - Intermittent difficulties with coordination and speech. Regular blood tests, including thyroid-stimulating hormone (TSH) levels and complete blood count, yielded normal results. However, during a consultation with a private physician, I received some "abnormal" findings: - Elevated TNF alpha levels, - Increased levels of M3 muscarinic acetylcholine receptor autoantibodies, - Extremely high concentrations of vitamin B12. The doctor indicated that these results suggest there may be moderate systemic inflammation, but he could not determine the underlying cause. Do these findings have legitimate significance, and should I consider discussing this further with my general practitioner?
Understanding the Origins of Focal Necrosis in My Liver
As a 33-year-old male, standing 5 feet 10 inches tall and weighing 200 pounds, I have a medical background that includes Crohn's disease and a recent diagnosis of Non-Hodgkin's lymphoma (specifically DLBCL). In my most recent PET/CT scan, I was informed that a small section of segment 6 of my liver exhibited hypodensity. It’s worth noting that my cancer has not metastasized to my liver, and apart from mild non-alcoholic fatty liver disease (NAFLD), my liver function appears to be satisfactory. I avoid any activities that might harm my liver health. This finding prompted my oncologist to schedule an MRI of my abdomen, which unfortunately did not yield any definitive results. Initially, my oncologist suspected a hemangioma, while the radiologist, who later performed a biopsy post-MRI, speculated that it could be an infection. Ultimately, the biopsy indicated the presence of focal necrosis, which essentially refers to a localized area of dead tissue—around 2 cm in size, if I recall correctly. This leaves me wondering about the cause behind this condition. To provide some context, I experienced a bowel perforation on January 8, 2025, which led to peritonitis and an urgent small bowel resection the same day. Following that event, my treatment regimen included one cycle of RCVP (Rituximab, Cyclophosphamide, Vincristine, and Prednisone), five cycles of Pola-R-CHP, and two cycles of Rituxan alone. My questions are: Is the focal necrosis a consequence of the peritonitis, the chemotherapy, or is it attributable to a different factor altogether?
Should I Seek Immediate Help?
Hello, I'm a 15-year-old female, Lately, I've been encountering a peculiar sensation where it feels as if everything around—and including—myself is vibrating side to side, even while I'm completely still. These episodes typically last for about three minutes when I'm sitting and continue while I'm lying down. To explain it further, I perceive this unsettling experience as my body swaying side to side, and when I glance around, it seems like my surroundings are shaking. My vision feels like it's malfunctioning, as if my eyes are erratically jolting back and forth between the sides, although I believe they remain motionless. While it’s not painful, the sensation is quite uncomfortable and feels very genuine. I want to clarify that I've never taken drugs or received any medications for health issues. Although I have my suspicions about possibly experiencing depersonalization-derealization disorder, that's a different topic altogether. This phenomenon has been going on for some time now, and I have a doctor's appointment scheduled for later this week. However, I've noticed that the occurrences are becoming more frequent, leading me to contemplate whether I should seek medical attention sooner. If there are any inquiries, I'm more than willing to provide additional details. I apologize if this message is a bit perplexing or lengthy. I'm just feeling somewhat anxious about the situation.
Experiencing Dizziness, Fast Heartbeat, and Low Blood Pressure
45-year-old female, height 5'3", weight 182 lbs. I have type 2 diabetes that's managed without insulin and has no complications; my A1C levels have consistently remained below 6.0. Additionally, I live with PTSD, autism (level 1), and ADHD. Current medications include: Jardiance, Mounjaro, Metformin, Fenofibrate, Guanfacine, Quetiapine for sleep issues, and Prasozin at 1 mg for managing nightmares. I occasionally take Klonopin, up to twice weekly for panic attacks, along with Melatonin. There haven’t been any alterations to my medication regimen for over a year. I’ve been experiencing increased dizziness upon standing, which has become more frequent over the past three months. In that same timeframe, I have lost approximately 8 pounds. A few years back, I encountered a similar episode at work where, after sitting down, my Apple Watch flagged an elevated heart rate, prompting me to be sent home with a directive to obtain medical clearance. An emergency room visit followed; unfortunately, the treatment I received was less than ideal. They attempted to administer 10 units of insulin without properly checking my blood sugar despite my last meal being at 5 AM. When they finally did take my reading, it showed 75, leading them to withhold the insulin, which further compounded a very negative experience. I wore a heart monitor during this time, underwent a treadmill stress test, and had an echocardiogram. Ultimately, the doctors found nothing significant, resulting in a lack of further investigation. Since then, episodes of dizziness appeared sporadically, but during a visit, my primary care provider's nurse observed one instance where my heart rate spiked again. I subsequently had an ECG performed, and while one of the values was slightly off, I later learned that electrode misplacement could often cause such discrepancies in obese patients. I was referred to a cardiology specialist, where I underwent another ECG and echocardiogram and was asked to wear a Holter monitor for thirty days. However, due to the infrequency of my episodes, none were recorded during that time, and both tests returned normal results. I was released from cardiology with a clean bill of health, albeit still classified as obese. My PCP speculated it couldn’t be POTS, and since cardiology had cleared me, she expressed no immediate concern. The situation has worsened, with dizzy spells now occurring multiple times a day. Unfortunately, my doctor appointments keep getting postponed due to her illness or vacation plans, with the next available appointment being weeks away; it was rescheduled from July 30 to September 26. These dizzy spells lead me to sit down on the floor or find a nearby seat at least once daily. I’ve experienced multiple falls, and I suspect I may have fainted last week while alone. The dizziness is unpredictable, but I was able to monitor my blood pressure during one episode. Before standing, my reading was 98/66, which is normal for me under non-stressful conditions. After standing, I felt dizzy, sat back down and tested again, receiving a reading of 75/47. While I did notice an increase in heart rate, I couldn’t remember the exact number since my app does not track that. I’m uncertain about which doctor to approach next. I cannot return to cardiology since I've been discharged, and my hospital network requires referrals for specialist visits, which can take weeks just to obtain, with appointment wait times stretching for months. My partner, who lives far away, has been urging me to seek medical attention, so after another fall yesterday, I reached out to my clinic. When they followed up half an hour later, my blood pressure was recorded at 96/57. They advised me to head to the ER, reminding me not to drive myself, which feels unnecessary since such incidents are often resolved by the time I would arrive, plus I lack alternative transportation. These dizzy spells are definitely not the result of low blood sugar, as I’ve confirmed my blood glucose remains stable during episodes, consistently within the target range given my eating habits. I have the option to seek specialists outside of my hospital network who don’t require referrals, but changing providers causes me significant anxiety due to my autism. Nevertheless, I’m considering this option if I can find someone who can see me sooner. The question remains: who should I approach?
