We report 9 patients with an isolated infarct of the anterior part of the rostral cerebellum, ie, the territory of the lateral branch of the superior cerebellar artery. Clinicoanatomic correlations are based on CT, MRI, or both in 8 patients and on pathologic data in the ninth. The main clinical features were ipsilateral dysmetria and axial lateropulsion, dysarthria, and unsteadiness. In 1 patient, the clinical presentation mimicked a lacunar stroke (dysarthria and clumsy hand syndrome). There were no edematous cerebellar infarcts with signs of brainstem compression, and all patients spontaneously improved without significant sequellae. Angiography in 2 patients and pathologic examination of arteries in 1 patient disclosed no occlusion in the vertebrobasilar system. Six patients had a cardiac source of emboli. In conclusion, infarcts of the anterior part of the rostral cerebellum can be regarded as a benign condition in which there is, frequently, a cardiac source of emboli.
我们报告了9例仅累及小脑嘴侧前部梗死的患者，即小脑上动脉外侧支供血区域。8例患者的临床解剖学关联基于CT、MRI或两者，第9例基于病理数据。主要临床特征为同侧辨距不良和轴向侧推、构音障碍及步态不稳。1例患者的临床表现类似腔隙性卒中（构音障碍和手笨拙综合征）。不存在有脑干受压征象的小脑梗死水肿，所有患者均自发改善，无明显后遗症。2例患者的血管造影及1例患者的动脉病理检查显示椎基底系统无闭塞。6例患者有心脏栓子来源。总之，小脑嘴侧前部梗死可视为一种良性疾病，其栓子来源通常为心脏。
