Info

MRI demonstrates a right pontine popcorn lesion with a complete surrounding hemosiderin ring with complex signal intensity due to blood product of varying age. The lesion is consistent with a cavernous malformation. Note the presence of an associated developmental venous anomaly seen only on T1 C+ sequence, draining the right cerebellar hemisphere. Susceptibility sequence failed to detect other similar lesions.

Case Discussion

Typical appearances of a cavernous malformation (Zabramski type 2) with an associated DVA, a very common finding.
