To describe a rare case of a thrombosed (false) aneurysm of the meningolacrimal branch of the middle meningeal artery.
Interventional case report.
A 36-year-old man presented with unilateral proptosis of sudden onset after minor head trauma. Imaging showed an apical oval mass interposed between the superior and lateral rectii muscles in close proximity to a vessel about 0.5 mm in diameter. On carotid angiography, the mass did not fill with contrast material, but the adjacent artery proved to be the meningolacrimal branch of the middle meningeal artery. This pseudoaneurysm was successfully evacuated surgically, and the overlying vessel was ligated.
Orbital aneurysms are exceedingly rare and almost exclusively derived from the ophthalmic artery. To the best of our knowledge, this is the first reported case of an intraorbital aneurysm arising from the meningolacrimal branch of the middle meningeal artery which was successfully managed surgically.
描述硬脑膜中动脉脑膜泪支血栓形成（假性）动脉瘤的罕见病例。
介入病例报告。
一名 36 岁男性，头部轻微外伤后突发单侧眼球突出。影像学检查显示，在上方和外侧直肌之间有一个顶端呈椭圆形的肿块，与一条直径约 0.5 毫米的血管非常接近。颈动脉造影显示，肿块未充盈造影剂，但相邻动脉被证实为硬脑膜中动脉脑膜泪支。该假性动脉瘤成功地通过手术排空，并且对覆盖的血管进行了结扎。
眼眶动脉瘤极为罕见，几乎全部源自眼动脉。据我们所知，这是首例报道的源自硬脑膜中动脉脑膜泪支的眶内动脉瘤，通过手术成功治疗。
