Twenty adult patients with orbital pseudotumor were studied with orbital venography and magnification arteriography. Computed tomography (CT) scans were obtained in 14 patients. Occlusive and constrictive changes of the proximal segments of the superior ophthalmic veins were the most frequent vascular abnormalities. The affected ophthalmic arteries were often attenuated but not occluded. Myositis and surrounding connective tissue inflammatory changes are thought to result in sufficient mass effect to cause the venous stasis with narrowing and subsequent occlusion. Such venographic changes are not distinctive for orbital pseudotumor but may also be seen in cases of thyrotoxicosis, Tolosa-Hunt syndrome, and orbital tumors.
对20例眼眶假瘤成年患者进行了眼眶静脉造影和放大动脉造影研究。14例患者进行了计算机断层扫描（CT）。眼上静脉近端节段的闭塞性和狭窄性改变是最常见的血管异常。受累的眼动脉常变细但未闭塞。肌炎和周围结缔组织炎症改变被认为会产生足够的肿块效应，导致静脉淤滞、狭窄并随后闭塞。这种静脉造影改变并非眼眶假瘤所特有，在甲状腺毒症、托洛萨-亨特综合征和眼眶肿瘤病例中也可见到。
