摘要

目的：探讨永存镰状窦的MRI、MSCT表现，以提高对永存镰状窦的认识和诊断。方法：收集2005年1月—2014年7月17例临床及影像学确诊为永存镰状窦患者的临床及影像学资料，结合文献进行回顾性分析，研究永存镰状窦的MRI、MSCT表现。结果：17例永存镰状窦患者中，9例行常规MRI检查，T2WI矢状位均显示大脑大静脉池后部条状流空血管影自大脑大静脉向上引流至上矢状窦中、后三分之一处；2例行磁共振静脉成像（MRV），显示大脑大静脉经开放的镰状窦向上引流入上矢状窦；1例行MRI增强扫描，示上矢状窦与大脑大静脉池间强化血管影相连通。5例行CTA扫描，静脉期可见大脑大静脉或直窦前部与上矢状窦后三分之一处相连的条带状强化血管样结构。结论：永存镰状窦MRI、MSCT表现具有特征性，常规MRI、MRV、MRI增强与CTA均可准确反映永存镰状窦的形态、位置及其与周围结构的关系，有助于对永存镰状窦全面综合评价。

Abstract

Objective: To investigate the MRI and MSCT characteristics of persistent falcine sinus, in order to improve the understanding and diagnosis of it． Methods: Clinical, MRI and MSCT data were collected from 17 patients with persistent falcine sinus confirmed by MRI and MSCT from January 2005 to July 2014． Results: MRI cerebral conventional examination was performed in 9 cases, and T2WI sagittal view showed an enlargement vascular flow void signal arising from the great cerebral vein and draining into the superior sagittal sinus in its middle and posterior third part. Magnetic resonance venous imaging(MRV) clearly showed the great cerebral vein draining into the superior sagittal sinus through the opening falcine sinus in 2 cases． Enhanced T1WI also clearly showed the superior sagittal sinus connected with the cisternae venae magnae cerebri by an enhanced blood vessel in 1 case． Five patients underwent CTA, and falcine sinuses were seen as ribbon or yardstick-like vascular structures between the vein of Galen or straight sinus and the posterior third part of the superior sagittal sinus. Conclusion: MRI and MSCT imaging of persistent falcine sinus is characteristic． Conventional MRI combined with MRV, enhanced MRI and MSCT can show the appearance more clearly, position of the persistent falcine sinus and its relationship with surrounding structures, contributing a lot to its comprehensive evaluation．
