目的探讨螺旋CT对颅内皮样囊肿的诊断价值.方法收集10例经手术病理证实的颅内皮样囊肿患者资料,对其CT表现、病因、病理和临床特征进行回顾性分析.结果病灶位于后颅窝5例,鞍旁3例,鞍上1例,颞窝1例;病灶形态呈圆形或类圆形,轮廓分界清晰,周围无水肿,7例呈欠均匀的低密度(密度低于脑脊液)脂肪影,CT值-6 ～ 80 HU,1例病灶边缘可见少量钙化,2例于低密度病灶内可见不规则团状毛发样高密度影,1例病灶临近颅板受压变薄、变形.结论颅内皮样囊肿有典型的CT表现,结合临床综合分析可作出准确诊断.

Objective To explore diagnosis value of spiral CT on intracranial dermoid cyst based on retrospective analysis.Methods 10 cases of intracranial dermoid cyst were enrolled in and confirmed by surgery and pathology.The retrospective analysis was based on the CT manifestations,causes,pathological and clinical features.Results Among the 10 cases,5 lesions were located in the posterior cranial fossa,3 in besides saddle,1 in up saddle and 1 in the temporal fossa.The morphology of nidus was round or round like with clear boundary.There was no edema around the nidus.Fat was found in 7 cases appeared hypodensity with insufficiency uniformity on CT,and the density was lower than that of cerebrospinal fluid with CT value ranged from-6 HU to 80 HU.There was a few calcification on the edge in 1 case.Hyperdensity irregular and lumpy hair-liked shadow was found in 2 hypodensity cases.1 lesion closed to the cranial plate was compressed thin and buckled.Conclusions Intracranial dermoid cyst has typical CT manifestations.It will be an accurate diagnosis based on clinical analysis and CT manifestations.
