Cerebellar infarctions secondary to cranio-cervical anomalies: a case report.
We report a case of cerebellar infarctions which occurred in the territories of the bilateral posterior inferior cerebellar arteries. This case was complicated with cranio-cervical anomalies composed of assimilation of the atlas, atlanto-axial dislocation, and basilar impression. The 40-year-old male patient had no detectable risk factors predisposing to atherosclerotic arterial occlusion or cardiogenic embolism, and there were no angiographic findings of atherosclerosis. It was, therefore, postulated that the cerebellar infarctions were secondary to those cranio-cervical anomalies. The developing mechanism is discussed.
