颅内表皮样囊肿约占所有颅内肿瘤的0.2％～l,8％,发病机制分先天性和获得性。肿瘤生长缓慢,起病表现隐匿,桥小脑角肿瘤多为神经根痛,幕上肿瘤则以颅内占位性病变所致的临床表现。头颅CT有助于诊断,MRI液体衰减反转恢复序列（Flair）和弥散加权成像（DWI）及弥散加权平面回波成像具有鉴别诊断意义。至今,手术是其唯一治疗办法,术中使用显微技术和内窥镜辅助有助于肿瘤切除和神经功能保护,其预后较好。
Intracranial epidermoid cyst accounts for about 0.2% of all intracranial tumors ~ l, 8%, pathogenesis sub-congenital and acquired. Tumor growth is slow, the performance of occult onset, mostly in the cerebellopontine angle of the root canal pain, supratentorial tumor lesions caused by intracranial clinical manifestations. Head CT is helpful in the diagnosis of MRI, and Flair and DWI and DWI are of significance for differential diagnosis. So far, surgery is its only treatment, intraoperative use of microscopy and endoscopy assisted tumor resection and neurological protection, the prognosis is good.
