| 摘 要： | 目的:评价颅内先天性胆脂瘤的MRI影像学特征.方法:回顾性复习20例经手术与病理证实的颅内先天性胆脂瘤.术前均行MRI平扫与增强检查.结果:肿瘤发生于桥小脑角区11例,鞍上区3例,鞍旁区3例,四脑室1例,侧脑室1例,小脑蚓部1例.典型表现者16例,占80%,表现为T1WI低信号,T2WI高信号;非典型者4例,占20%,T1WI表现为欠均匀高信号,T2WI表现为低信号.增强扫描,16例肿瘤不强化,4例边缘强化.结论:MRI对诊断颅内先天性胆脂瘤有重要价值.

| Abstract: | Objective:To summarize the MRI imaging features of intracranial epidennoid cyst.Methods:20 intracranial epidermoid cysts pathologically confirmed were analyzed retrospectively.Results:Sixteen intracranial epidermoids cysts exhibited homogeneously low signal intensity on T1WI and high signal intensity on T2WI (80%),and only 4 cases showed high signal intensity on T1WI and low signal intensity on T2WI (20%).After contrast enhancement,16 cases had no obvious enhancement while 4 cases had slightly rim-like enhancement.Con- clusion:MRI is valuable in making diagnosis of intracranial epidermoid cysts. |
