Abstract

Cavernous hemangiomas occur very rarely in the cavernous sinus and are difficult to diagnose preoperatively. MR images obtained in five patients with surgically verified cavernous hemangiomas in the cavernous sinus were reviewed. MR images showed hypointensity on T1-weighted images and well-defined hyperintensity on T2-weighted images with marked homogeneous enhancement after contrast material administration. We report the characteristic MR imaging observations for these lesions.

摘要

海绵状血管瘤在海绵窦中极为罕见,术前难以诊断。回顾了5例经手术证实为海绵窦海绵状血管瘤患者的磁共振成像(MR)图像。MR图像在T1加权像上呈低信号,在T2加权像上呈边界清晰的高信号,注入对比剂后有明显的均匀强化。我们报告了这些病变的特征性MR成像表现。
