A 43-year-old man developed cerebellar infarction due to atlantoaxial dislocation associated with os odontoideum. Cervical X-ray films confirmed os odontoideum, and conventional angiography revealed irregular narrowing of the right vertebral artery at the axis level. A correlation between the vertebral artery lesion and atlantoaxial instability was shown with 3-dimensional (3-D) computed tomographic (CT) angiography. This is the first case of atlantoaxial dislocation with vertebral artery stenosis demonstrated 3-D CT angiography. 3-D CT angiography can support the conventional angiography with respect to the diagnosis and management of vertebral artery insufficiency associated with occipitocervical deformity.
一名43岁男性因齿突骨导致寰枢椎脱位而发生小脑梗死。颈椎X线片证实为齿突骨，传统血管造影显示右侧椎动脉在枢椎水平出现不规则狭窄。三维（3-D）计算机断层扫描（CT）血管造影显示了椎动脉病变与寰枢椎不稳定之间的相关性。这是首例通过三维CT血管造影显示椎动脉狭窄的寰枢椎脱位病例。三维CT血管造影在枕颈畸形相关椎动脉供血不足的诊断和治疗方面可辅助传统血管造影。
