Cavernous malformations (CMs) arising from the optic nerve and chiasm are extremely rare. The authors present a case of 39-year-old woman with CMs of the optic chiasm. She was referred due to sudden onset of bitemporal hemianopsia and headache, the so-called 'chiasmal apoplexy'. MRI findings suggested a diagnosis of hemorrhage and vascular malformation of the optic chiasm. Pterional craniotomy revealed an intrachiasmatic cavernous malformation with hemorrhage. The malformation was totally excised, but field deficits remained unchanged after surgery.
起源于视神经和视交叉的海绵状血管畸形极为罕见。作者报告了一例39岁患有视交叉海绵状血管畸形的女性病例。她因突然出现双颞侧偏盲和头痛(即所谓的“视交叉卒中”)前来就诊。磁共振成像(MRI)检查结果提示视交叉出血和血管畸形。经翼点入路开颅手术发现视交叉内有伴出血的海绵状血管畸形。该畸形被完全切除,但术后视野缺损仍无改善。
