摘要

目的:分析肥大性下橄榄核变性(HOD)的MRI表现,以提高对该病的认识。方法:对8例HOD的MRI表现及引起该病的病因进行回顾性分析。自原发病变出现到MRI检查时间为3~30个月。结果:MRI图像均表现为下橄榄核(ION)部位T2WI高信号,T1WI呈等或稍低信号,有3例双侧ION部位出现高信号,5例ION体积有不同程度增大。8例病人中原发病变为中脑梗塞3例,桥脑出血2例,小脑出血2例、梗死1例。结论:MRI能清晰显示Guillain-Mollaret三角区病变所致ION变化,提高对该病的认识可以避免误诊。

Abstract

Objective: To analyze MRI characteristics of hypertrophic olivary degeneration(HOD) in order to improve our knowledge for this disease. Materials and Methods: MRI findings in all 8 patients with HOD and the inciting lesions were reviewed. The intervals from ictus to MR scan were 3~30 months. Results: The region of inferior olivary nucleus(ION) presented high intensity on T2WI and iso- or mild hypo-intensity on T1WI in all 8 patients. Bilateral ION showed high-signals in 3 cases. Enlargement of the ION in 5 patients also was noted. The primary lesions were also located-three with midbrain infarctions, two with pontine tegmental hemorrhages and two with hemorrhages, one with infarction in the cerebellum. Conclusion: MR images may clearly demonstrate the changes of ION in patients with a lesion in the triangle of Guillain and Mollaret. Misdiagnosis may be avoided by improving the recognizition for this disease.
