MRI through the temporal lobes demonstrates bilateral cystic regions orof variable signal intensity. On the right the lesion is similar to CSF on all sequences, whereas on the left the content is high T2, intermediate T1 and does not attenuate on FLAIR. Both sides demonstrate peripheral signal drop out suggesting hemosiderin deposition. There is little if any peripheral enhancement, and no restricted diffusion.
