A 9-year-old child presented with right eye swelling and bluish discoloration over the periorbital region. MR and CT displayed prominent vessels within the orbit and in the facial region, suggesting a carotid-cavernous fistula. Doppler ultrasound indicated the vascular engorgement was not secondary to a proximal arteriovenous shunt. Arteriography with its inherent time sequence image capability prompted the proper diagnosis of bilateral atresia of the sigmoid sinuses.
一名9岁儿童出现右眼肿胀及眶周区域青紫色改变。磁共振成像(MR)和计算机断层扫描(CT)显示眼眶及面部区域血管明显,提示存在颈内动脉海绵窦瘘。多普勒超声显示血管充血并非继发于近端动静脉分流。具有固有时间序列成像能力的动脉造影提示正确诊断为乙状窦双侧闭锁。
