This case demonstrated a typical cerebral cavernous malformation (cavernoma)

A popcorn-like lesion with T2 hypointense ring of hemosiderin is virtually diagnostic of cavernous malformation (cavernoma) of the brain.

Cavernous malformations (cavernoma) could be multiple, so T2* or SWI-GRI sequence must be done particularly in patients with spontaneous hemorrages. 

The annual hemorrhage was 0.6% in patients who never had a symptomatic hemorrhage. Patients who had prior hemorrhage have a higher (4.5%) annual hemorrhage rate.

The differential diagnosis of popcorn- likle lesions are: A-V malformation, hemorrhagic and calcified neoplasms.
