摘要
目的探讨CT和MRI在脉络膜裂囊肿中的诊断价值。方法对25例脉络膜裂囊肿的CT和MRI表现进行回顾性分析。结果25例均位于脉络膜裂内，囊肿呈圆形或类圆形、边界清晰的脑脊液密度或信号，灶周无水肿，增强扫描无强化，随访无变化。结论CT和MRI均可检出脉络膜裂囊肿，但在诊断和鉴别诊断方面，MRI优于CT。
Objective To discuss the value of CT and MRI scans in the diagnosis of the choroidal fissure cysts. Methods CT and MRI findings of 25 patients with choroidal fissure cyst were analyzed restrospectively. Results The cysts were situated within the choroidal fissure in all cases, representing as round cystic lesion with clear border and homogenous signal intensity or density identical to CSF, without associated edema or evidence enhencement. Conclusion Choroidal fissure cyst could be detected on both CT and MRI, but MRI is better than CT in diagnosis and differential diagnosis of choroidal fissure cyst.
