We report a rare case of aberrant internal carotid artery in the middle ear. The patient was a 30-year-old man with pulsatile tinnitus. MRA and 3D-CTA revealed an aberrant course of the internal carotid artery in the middle ear. 3D-CTA proved useful for radiographic diagnosis, leading to the observation of an aberrant internal carotid artery passing the foramen. We discuss the diagnosis and management of such patients.
我们报告一例罕见的中耳内颈内动脉走行异常病例。患者为一名30岁男性，患有搏动性耳鸣。磁共振血管造影（MRA）和三维计算机断层血管造影（3D-CTA）显示颈内动脉在中耳走行异常。3D-CTA被证明对影像学诊断有用，得以观察到颈内动脉通过该孔。我们讨论了此类患者的诊断和治疗。
