We report a case of bilateral aplasia of the internal carotid arteries. A 59-year-old man was admitted with generalized convulsions. Computed tomography and magnetic resonance imaging of the head showed normal findings. Three-dimensional computed tomography, angiography, and intra-arterial digital subtraction angiograms showed bilateral aplasia of the internal carotid arteries. The bilateral ophthalmic arteries were filled from the hypoplastic carotid arteries, and the anterior and middle cerebral arteries were filled from the basilar artery via the posterior communicating arteries. Associated with this bilateral aplasia of the internal carotid arteries, intracranial aneurysms and megadolicho-basilar anomaly were reported. Angiography is to be recommended if IC aplasia is suspected.
我们报告一例双侧颈内动脉发育不全的病例。一名59岁男性因全身性惊厥入院。头部计算机断层扫描和磁共振成像显示结果正常。三维计算机断层扫描、血管造影和动脉内数字减影血管造影显示双侧颈内动脉发育不全。双侧眼动脉由发育不全的颈动脉供血，大脑前动脉和大脑中动脉由基底动脉经后交通动脉供血。据报道，该双侧颈内动脉发育不全病例伴有颅内动脉瘤和巨长基底动脉异常。如果怀疑颈内动脉发育不全，建议进行血管造影。
