患者男,49岁,右手活动欠灵活1个月入院,既往有胃大部切除手术,查体:右手指鼻及跟膝胫试验欠稳准,右侧巴氏征可疑阳性。磁共振成像(magnetic resonance imaging,MRI)检查示:桥脑(左侧为主)可见一类椭圆形异常信号灶,病灶信号混杂、分层,前部(大部分)为T1WI高、T2WI高信号,后部为T1WI等、T2WI低信号,病灶边缘清楚,范围约2.4 cm×1.8 cm,
The patient was a 49-year-old man. He was admitted to the hospital with a lack of right hand activity for 1 month. He had had a subtotal gastrectomy. His examination showed that the right finger and nose and the knee joint test were not stable and the right Pakistani sign was suspiciously positive. Magnetic resonance imaging (MRI) examination showed that there was a type of elliptical abnormal signal lesion in the pons (main left side). The lesion signals were mixed and stratified. The anterior (most) signals were high on T1WI and high on T2WI. , The posterior is T1WI, T2WI low signal, the lesion edge is clear, the range is about 2.4 cm × 1.8 cm,
