| 摘 要： | 目的：探讨颅内非感染性囊肿MRI影像特点,用以指导临床诊断及鉴别诊断。方法：回顾性分析170例颅内非感染性囊肿的MRI资料,其中部分囊肿经手术或病理证实,总结病变发病部位、形态、MRI信号特点。结果：92例蛛网膜囊肿,位于中颅窝颞前部53例;表皮样囊肿24例,22例位于桥前池或桥小脑角区,DWI均表现为高信号;14例松果体囊肿,全部位于松果体区;12例血管周围间隙,10例位于底节区或中脑;10例Rathke裂囊肿,均位于鞍内或鞍上;8例脑穿通畸形,均位于大脑半球;5例脉络膜裂囊肿,均位于颞叶;4例室管膜囊肿,均位于侧脑室三角区;1例脉络丛囊肿位于侧脑室三角区。蛛网膜囊肿、血管周围间隙、脑穿通畸形、脉络膜裂囊肿、室管膜囊肿内液体FLAIR序列上被抑制,表皮样囊肿、松果体囊肿、Rathke裂囊肿、脉络丛囊肿内液体FLAIR序列不被抑制。结论：蛛网膜囊肿是颅内常见囊肿;囊肿发病部位、弥散加权成像、水抑制序列对诊断及鉴别诊断有帮助。
