Abstract

A case of intraorbital arteriovenous malformation presenting with visual loss, exophthalmos, and chemosis of the right eye is reported. Enhanced computer tomography and magnetic resonance imaging showed extraocular muscle enlargement and vascular abnormality in the right retrobulbar space. Angiography revealed an abnormal intraorbital vascular stain with an extremely dilated right ophthalmic artery. Total removal of the intraorbital contents was performed after unsuccessful endovascular and surgical treatment of arteriovenous malformation (AVM). Histopathological examination disclosed an AVM in the retrobulbar fatty tissue with extension into the extraocular muscles and optic nerve.

摘要

报告了一例眼眶内动静脉畸形病例，表现为右眼视力丧失、眼球突出和结膜水肿。增强计算机断层扫描和磁共振成像显示右眼球后间隙眼外肌增大和血管异常。血管造影显示眼眶内血管染色异常，右侧眼动脉极度扩张。在动静脉畸形（AVM）的血管内和手术治疗失败后，进行了眼眶内容物全切术。组织病理学检查显示球后脂肪组织中有一个AVM，并延伸至眼外肌和视神经。
