We describe a case of bilateral olivary hypertrophy and palatal tremor after unilateral cerebellar infarction. Hypertrophic olivary degeneration (HOD) is associated with hypersignal in the inferior olivary nucleus (ION), on T2-weighted images. HOD has been more often observed ipsilaterally to a central tegmentum tract lesion or contralaterally to a dentate nucleus or a superior cerebellar peduncle lesion. Double innervation of each ION from either dentate nucleus may have underlied the imaging and clinical findings in this 63 year-old male patient.
我们描述了一例单侧小脑梗死后出现双侧橄榄体肥大和腭震颤的病例。在T2加权图像上，肥大性橄榄体变性（HOD）与下橄榄核（ION）的高信号有关。HOD更多见于中脑被盖束病变的同侧或齿状核或上小脑脚病变的对侧。来自齿状核的对每个ION的双重神经支配可能是这位63岁男性患者影像学和临床发现的基础。
