Abstract

A 55-year-old man with diabetes mellitus developed diplopia and experienced difficulty in moving his eyes in the vertical plane, especially downward. Horizontal movement of each eye was normal with exotropia. Magnetic resonance imaging revealed small and high signals on both sides of the midbrain near the interstitial nucleus of Cajal (INC). Based upon the recent experimental evidence, we speculate that bilateral lesions involving the INC may have caused downward gaze palsy in our patient.

摘要

一名55岁的糖尿病男性出现复视，并且在垂直平面上，尤其是向下移动眼睛时遇到困难。每只眼睛的水平运动正常，但有外斜视。磁共振成像显示中脑两侧靠近 Cajal 间质核（INC）处有小的高信号。基于最近的实验证据，我们推测双侧累及INC的病变可能导致了我们患者的向下凝视麻痹。
