Abstract

MRI aspects of olivary pseudohypertrophy (OH) following pontocerebellar lesions of different etiology and localization are reviewed. OH is characterized by unilateral or bilateral enlargement of the inferior olivary nucleus and increased signal intensity in T2- and, especially, in proton-density (PD)-weighted images. Correlations between the extent and the uni- or bilateral presence of olivary hypertrophy and the localization of the primary pontocerebellar lesions are discussed.

摘要

本文综述了不同病因和部位的脑桥小脑病变后橄榄体假性肥大（OH）的MRI表现。OH的特征是下橄榄核单侧或双侧增大，在T2加权像尤其是质子密度（PD）加权像上信号强度增加。文中讨论了橄榄体肥大的范围、单侧或双侧出现情况与原发性脑桥小脑病变部位之间的相关性。
