颌面部海绵状血管瘤的MRI诊断价值

目的探讨颌面部海绵状血管瘤的MRI表现和诊断价值。方法回顾性分析我院经手术和病理证实的31例颌面部海绵状血管瘤的MRI表现。结果病变分布在腮腺咬肌区13例,颊部及颧颞部12例,眶部3例,唇部3例。3例为椭圆形或类圆形,2例为梭形,其余26例均表现为团状或片状的不规则形。T1WI上20例表现为长T1信号,7例为等T1信号,4例为稍长T1信号,在T2WI上27例表现为长T2高信号,4例为稍高信号。结论MRI可以明确颌面部海绵状血管瘤的诊断,并能明确病变的形态和范围,为临床诊断及手术方案的制订提供可靠的依据。

Diagnostic Value of MRI for Cavernous Hemangioma in Maxillofacial Region

Objective To study the manifestations and diagnostic value of MRI for cavernous hemangioma in maxillofacial region.Methods Thirty-one cases of cavernous hemangioma in maxillofacial region proved pathologically were retrospectively analyzed.Results The lesions localized in parotideomasseteric region in 13 cases,in buccal and zygomalicotemporal region in 12 cases,in orbital area in 3 cases and labium in 3 cases.The lesions appeared as ellipse or round-like in 3 cases,fusiform in 2 cases,mass or flat irregular shape in 26 cases.On MRI,20 cases showed long T1 signal intensity,4 cases were slight long T1 and 7 cases were equal T1;on T2WI,27 cases showed high signal intensity and 4 were slight signal intensity.Conclusion The diagnosis of cavernous hemangioma in maxillofacial region can be verified and the shape,the extent of lesion can also be showed by MRI.It provides a reliable basis for clinical diagnosis and operative plan.
