Case Discussion
Cerebral cavernous venous malformations or cavernomas are common cerebral vascular malformations. They have characteristic appearances on MRI with popcorn appearance surrounded with the hypointense rim of hemosiderin on T2 and blooming on GRE/ SWI.
They may be associated with developmental venous anomaly (DVA) and must be reported.
