摘　　要：颅内表皮样囊肿是一种少见的先天性病变,桥脑小脑角是肿瘤常见的部位之一。CT描述病变呈低密度,边界清楚而且很少钙化,病灶无强化等特征,诊断一般无困难。本文报告6例经手术证实的颅内表皮样囊肿MRI的特征,并与CT表现相比较。MRI的临床应用为表皮样囊肿提供了一种新的诊断方法。Epidermoid tumours are congenital lesions. One of the tumour common sites isthe cerebellopontine angle. In computed tomography literatures, they have been des-cribed as low density, welldefined lesions which seldom show calcification or tissueenhancement. Generally it is not difficult to diagnosis. Six patients with intracranialepidermoid tumours underwent operation. The characteristic features of MRI in thiskind of tumours were described and compared with CT scan. MRI is a new diagnos-tic method for epidermoid tumours.
