【摘要】：目的探讨海绵窦海绵状血管瘤CT及MRI特征。方法回顾性分析6例经手术病理证实的海绵窦海绵状血管瘤患者的CT与MRI资料。6例均行MRI平扫+增强扫描及DWI扫描,1例行MRA检查;3例并行CT平扫+增强及CTA检查。结果肿瘤发生于右侧海绵窦3例,左侧3例。5例呈葫芦样横跨海绵窦,MR T1WI呈低信号;3例见小条片状等稍高信号,T2WI呈高信号,2例见小条状低信号,MR DWI上呈等或偏低偏高信号,ADC图呈低信号,增强扫描显著填充式强化。3例行CT检查,平扫呈均匀稍高密度,CTA或MRA可见病变包绕颈内动脉血管,病变未见明显供血血管;1例T1WI、T2WI像上呈混杂信号,CT可见明显钙化,增强扫描非钙化区域呈填充式强化特征。结论海绵窦海绵状血管瘤CT及MRI平扫及增强扫描影像表现具有特征性,认识这些特征并结合DWI及血管检查,有助于正确诊断。
[Abstract]:Objective to investigate the characteristics of CT and MRI of cavernous cavernous hemangioma in cavernous sinus. Methods Retrospective analysis of 6 cases of cavernous cavernous cavernous hemangioma of the cavernous sinus was performed by MRI plain scan + enhanced scan and DWI scan, 1 cases of MRA examination, 3 cases of parallel CT plain scan + enhancement and CTA examination. The tumor occurred in 3 cases of right cavernous sinus, left In the side 3 cases of.5, MR T1WI was low signal with hyacinth like cross cavernous sinus and low signal of MR T1WI, high signal of small strip like, high signal of T2WI, 2 cases with low signal of small strip, low signal on MR DWI, low signal in ADC map, and enhanced scan for enhanced.3 routine CT examination, uniform and slightly high density, CTA or MRA visible lesions wrapping There were no significant blood vessels in the internal carotid artery. 1 cases of T1WI, T2WI showed mixed signals, CT visible calcification, enhanced scan non calcification region showed filling enhancement characteristics. Conclusion cavernous sinus cavernous hemangioma CT and MRI scan and enhanced scan imaging features are characteristic, recognize these features and combine DWI and vascular examination. It is helpful to correct diagnosis.
