From: Uncommon cavernous malformation of the optic chiasm: a case report
Magnetic resonance images of the cavernous malformation of the optic chiasm (arrows). (A) The mass lesion demonstrated diffuse hyperintensity on T1-weighted imaging and mixed signal intensity; (B-C) The lesion was surrounded by a marked hypointense peripheral rim of hemosiderin on T2-weighted imaging. (D) No significant contrast enhancement was observed after the enhanced scanning.
