Cavernoma is a vascular hamartoma, which represents 10-20% of all central nervous system vascular malformations. The majority (80%) of them are supratentorial, while involvement of the cranial nerves and the optic pathways is extremely rare. The main clinical presentation of optochiasmatic cavernomas consists of chiasmatic apoplexy, which is a neurosurgical emergency. Here, we report a case in which the finding was incidentally detected in a 49-year-old man. We describe the imaging characteristics of the lesion in such a rare location, highlighting the role of magnetic resonance imaging (MRI) (specifically 3 Tesla) in the management of asymptomatic patients.
海绵状血管瘤是一种血管错构瘤，占所有中枢神经系统血管畸形的10%-20%。其中大多数（80%）位于幕上，而累及颅神经和视路极为罕见。视交叉海绵状血管瘤的主要临床表现为交叉性卒中，这是一种神经外科急症。在此，我们报告一例在一名49岁男性中偶然发现该病变的病例。我们描述了在如此罕见部位的病变的影像学特征，强调了磁共振成像（MRI）（特别是3特斯拉）在无症状患者管理中的作用。
