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。
Objective To investigate the MRI findings and diagnostic value of maxillofacial cavernous hemangioma. Methods The MRI findings of 31 cases of maxillofacial cavernous hemangiomas confirmed by operation and pathology in our hospital were analyzed retrospectively. Results The lesions were distributed in 13 cases of parotid masseter area, 12 cases of cheek and zygomatic temporal, 3 cases of orbital and 3 cases of lip. 3 cases were oval or oval, 2 cases were fusiform, and the remaining 26 cases showed irregular or patchy irregular shape. In T1WI, 20 cases presented with long T1 signal, 7 cases with equal T1 signal, 4 cases with slightly longer T1 signal, 27 cases with long T2 high signal on T2WI and 4 slightly higher signal on T2WI. Conclusion MRI can clearly diagnose cavernous hemangioma of maxillofacial region and can confirm the shape and scope of the lesion and provide a reliable basis for the clinical diagnosis and surgical plan formulation.
