Here is a case of long-term cortical blindness after a head trauma. Its etiology is ascribed to the cerebral vascular occlusion caused by the head trauma. From the findings of both a computerized tomography (CT) and magnetic resonance image (MRI), the lesions of our case are assumed to be in the bilateral areas 17 (Brodmann), some part of the bilateral areas 18, 19 (Brodmann) and bilateral optic radiations. On determination of the areas of these lesions, the location of the lesion in the bilateral areas 17 has been especially done by using the MRI. The MRI findings in our case have a full significance on this point.
这是一例头部外伤后长期皮质盲的病例。其病因归因于头部外伤导致的脑血管闭塞。从计算机断层扫描（CT）和磁共振成像（MRI）的检查结果来看，本病例的病变推测位于双侧17区（布罗德曼区）、双侧18区和19区（布罗德曼区）的部分区域以及双侧视辐射。在确定这些病变区域时，特别是通过使用MRI确定了双侧17区的病变位置。本病例的MRI检查结果在这一点上具有充分的意义。
