目的：探讨脉络膜裂蛛网膜囊肿的CT、MRI表现。方法：回顾分析经CT和MRI诊断为脉络膜裂蛛网膜囊肿的患者18例，CT轴位扫描12例，冠状扫描3例，其中增强扫描8例。MRI进一步检查6例，直接MRI检查3例。结果：18例病灶均发生于脉络膜裂区，右侧12例，左侧6例，均为单侧。直径为9～20mm，呈圆形或椭圆形，CT值5～20HU，增强扫描均无强化，与环池相连9例，灶周无水肿。结论：CT和MRI均可检出脉络膜裂蛛网膜囊肿，但在定性诊断和鉴别诊断方面MRI明显优于CT。
Objective： Swollen CT, the MPd performance of the purpose study choroidal fissure spider＇s web film bag.Methods： Review analysis was examine a patient by CT and MRI for swollen 18 of sufferer of the choroidal fissure spider＇s web film bag, the CT stalk scans 12, the coronal scans 3, among them strengthenning to scan 8. The MPd further checks 6, the direct MPd checks 3. Results All 18 focuses of are take place in the choroidal fissure area, 12 of right side, 6 of left side, all is a single side. The diameter is 9 - 20 mms, presenting the circular or ovals, the CT is worth 5 - 20 HUs, strengthen to scan and all did not enhance, with the wreath pond connect with each other 9, cooking stove week have no dropsy. Conclusions： CT and MRIs all can check a choroidal fissure spider＇s web film bag swollen, but in the aspects of settling sex diagnosis and discriminating to examine a patient obvious better than CT of MRI.
