A case of orbital hemangiopericytoma is reported in a 20-yr-old man presenting with decreased vision and painless proptosis of the left eye. This rare orbital tumor is reviewed in the literature, and in particular the neuroradiological findings, including those of computerized tomography (CT), magnetic resonance imaging (MRI), and angiography are detailed in the presented case. MRI was found to be useful both in delineating precise anatomical relationships between the optic nerve and the tumor, and in differentiating from cavernous hemangiomas, the most common vascular tumors of the orbit, with the combination of CT and angiography.
本文报告了一例20岁男性眼眶血管外皮细胞瘤病例，该患者表现为视力下降和左眼无痛性眼球突出。本文对这种罕见的眼眶肿瘤进行了文献综述，特别是详细介绍了该病例的神经放射学检查结果，包括计算机断层扫描（CT）、磁共振成像（MRI）和血管造影的检查结果。研究发现，MRI对于明确视神经与肿瘤之间的精确解剖关系以及与眼眶最常见的血管性肿瘤——海绵状血管瘤进行鉴别诊断很有帮助，同时结合了CT和血管造影检查。
