Do I need to worry about the mega cisterna magna in my MRI report?

Hello,

Welcome to icliniq.com.

Your MRI (magnetic resonance imaging) report (attachment removed to protect the patient's identity) shows most structures visible within normal limits except incident mega cisterna magna.

Cisterna magna is a normal CSF (cerebrospinal fluid) filled space on the backside of the brain. However, in many individuals, it can be more extensive, called mega cisterna magna, and that usually does not cause any symptom to the patient.

It needs to be differentiated from an arachnoid cyst or cerebellar atrophy, or dandy walker syndrome.

If any secondary cause of mega cisterna magna is found, that needs to be addressed.

But if it is idiopathic and without any other cause, mostly it is an incidental finding and does not cause symptoms.
