Hi,
Thank you for posting your query.
I have noted your brother's symptoms and
MRI brain findings.
First of all, I would like to reassure you that MRI findings do not suggest any serious abnormalities and there is no need to worry about that.
Giant cistern magna is a normal finding in many people and does not require any treatment. Most likely that is not the cause of headache.
The headache could be due to
migraine or
tension headache. These would respond to medications.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
