摘要
手结区位于端脑中央前回中上部,主管对侧手部运动功能,该区域梗死作为脑梗死的一种特殊类型,发病率不足脑梗死的1%,患者病后典型临床表现为单纯手部功能障碍,不伴随其他阳性体征,因此临床上难以与周围神经损伤鉴别,本文通过1例经典病例报告,就手结区梗死的典型临床表现、发病机制、MRI影像表现等进行阐述分析,旨在提高临床对于手结区梗死的诊断与鉴别诊断。
The hand knob area is located in the middle and upper part of the precentral gyrus of the telen-cephalon, and is responsible for the motor function of the contralateral hand. As a special type of cerebral infarction, the incidence of infarction in this area is less than 1% of cerebral infarction. The typical clinical manifestations of patients after the disease are simple hand dysfunction, without other positive signs. Therefore, it is difficult to identify with peripheral nerve injury in clinical prac-tice. In this paper, through a classic case report, the typical clinical manifestations, pathogenesis and MRI imaging manifestations of hand knob area infarction are described and analyzed, aiming to improve the clinical diagnosis and differential diagnosis of hand junction area infarction.
