【摘要】目的探讨脉络膜裂囊肿的影像学表现。方法对13例脉络膜裂囊肿的多排螺旋CT(MSCT)和MRI的表现进行了回顾性分析。结果13例囊肿均位于脉络膜裂内,表现为界限清楚的圆形、类圆形或梭形脑脊液样低密度影或信号影, 病灶周围均无水肿,增强扫描无强化, 最大者1.5cm×1.9cm×2.3cm,最小者0.5cm×0.8cm×1.0cm;短期内随访无变化。结论MSCT多平面重组(MPR)及MRI多方位成像相结合是脉络膜裂囊肿的重要方法。

    【Abstract】Objective To study the imaging findings of choroid fissure cyst. Methods Multi-slice CT(MSCT)

    and MRI findings of 13 patients with choroid fissure cysts were analyzed retrospectively. Results The cysts were situated within the choroidal fissure in all cases.Cysts were shown as round or ellipse and fusiform with sharp margins and homogeneous hypodensity on MSCT or cerebrospinal fluid-like signal intensity on MR imaging without enhancement. No change in the short term follow-up.Conclusion The MPR with MSCT and coronal and sagittal MR imaging is an important method in diagnosis of choroidal fissure cyst. ......
