I might have an incidental arachnoid cyst in the posterior fossa & i get chronic nose bleed when i blow my nose from the left nasal im scared from it?
A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more
Treatment for Hydrocephalus with posterior fossa cyst & VP Shunt insertion with pyogenic meaningitis?
I have a posterior fossa arachnoid cyst last known 1.7x 1.6x3cm severe headaches, "pressure" in head epilepsy memory loss confusion&others ..related?
We usually think not: However, there are cases where arachnoid cysts cause symptoms such as headaches and other types of both cognitive, motor, & cognitive problems which get better when the cyst is removed. But that doesn't happen often. Usually, they're benign & have been there since birth. They don't need to be removed unless testing/examination suggests otherwise. If you'd like a 1-1 consult please let me know. ...Read moreSee 1 more doctor answer

My gf had a NRM.Diagnose: arachnoid cyst posterior fossa and left maxillary sinusitis.What to do next?Treatment?Complications can apper?
Arachnoid cysts: These are congenital abnormalities often discovered incidentally and nothing need be done unless creating symptoms in which case discuss with a neurosurgeon. Sinusitis can be easily managed if it is acute, but radiologic changes can occur due to old inactive disease. She needs to see her doctor and discuss these things. Why was this imaging study done to begin with? ...Read more

Hi my husband 38 yrs old, has been suffering with headaches, blurred vision and imbalancing, he had a CT scan and MRI which shows having a arachnoid cyst in the posterior fossa region with mass effect something serious?
See specialist soon: I am hesitant to answer here for your husband for privacy reasons. But I will provide general comments. 1. Above symptoms happen from the arahnoid cyst with dilation of ventricles (inner chambers inside brain). There may be other reasons as well. 2. I would go see a neurosurgeon or neurologist very soon. Or go to ER for getting admitted to the hospital, so these problems can be addressed sooner. ...Read more
My 18 yo son has am arachnoid cyst in posterior fossa. He has a low heart rate and low blood pressure. What treatment is available?
Watch it: Many meningiomas don't change in size and it's safe to watch them over time. I would wonder why there was a ct scan or MRI done in the first place; if you were having symptoms that could be related to the meningioma then that might change things but in most cases meningiomas can be safely monitorred over time, and if you can avoid brain surgery you probably should! ...Read moreSee 1 more doctor answer

MRI report reads: fourth ventricle is in midline of the posterior fossa. What does that mean?What follow up is needed? I suffer from chronic headaches
Normal....: This is a normal finding. Ventricles in the brain are simply spaces filled with fluid. The location of these spaces are used to determine the brain's location in the skull. The "fourth ventricle" is in the cerebellum the back portion of the brain..the ventricle should be "midline" Your chronic headaches should be evaluated by a headache specialist/neurologist. ...Read moreSee 3 more doctor answers
What does Mild periventricular and subcortical abnormal T2 andsparing posterior fossa and brainstem mean on mri?
Nonspecific: Sometimes there are some changes or abnormal signal that we see on MRI in the deeper parts of the brain called the "white matter" that show up on an MRI scan. These changes can be non-specific meaning not diagnostic of any particular diseases or related to narrowing of small vessels or sometimes due to diseases such as multiple sclerosis. Happy to review the MRI through a virtual consult. Best! ...Read more
What should I expect going into a posterior fossa decompression surgery for chiari 1 malformation? Recovery time? Restrictions?
Chiari: Most surgery for chiari malformation is a decompressive operation. Surgery takes 3-4 hours. Hospital stay is usually 1 day in ICU and 1-2 days general care. I would recommend lifting less than 10 pounds for the first 2 weeks and less than 25 pounds after that. You will be asked to not bend your head lower than your waist. Recovery occurs in 6-8 weeks. ...Read moreSee 1 more doctor answer
