A 5-year-old boy was evaluated for a left retrotympanic mass found at otoscopy. Subsequent petrous bone CT and MR angiographic examinations demonstrated bilateral aberrant internal carotid, bilateral stapedial artery persistence, and bilateral duplicated internal carotid arteries. Imaging findings and their clinical relevance are discussed. A second case of unilateral aberrant internal carotid artery with a persistent stapedial artery is included for comparison.
一名5岁男孩因耳镜检查发现左侧鼓室后肿物而接受评估。随后的颞骨CT和磁共振血管造影检查显示双侧颈内动脉走行异常、双侧镫骨动脉持续存在以及双侧颈内动脉重复。本文讨论了影像学表现及其临床意义。还纳入了一例单侧颈内动脉走行异常伴镫骨动脉持续存在的病例以作比较。
