软组织血管瘤的MRI诊断与鉴别诊断

目的探讨软组织血管瘤的MRI表现及其特征。方法收集有完整MRI资料并经手术病理证实的软组织血管瘤16例,分析其大小、边缘、形态及信号特征。结果16例中,海绵状血管瘤9例,肿瘤直径2.0~5.0cm,边界清楚,T2WI多呈不均匀性高信号。肌肉内血管瘤5例,形态不规则,T2WI表现为高信号为主的混杂信号。蔓状血管瘤2例,血管迂曲扩张和肌肉萎缩是其特征性MRI表现。结论软组织血管瘤MRI表现有一定特征性,结合临床,可做出诊断。

MRI Diagnosis and Differential Diagnosis of Soft Tissue Hemangiomas

Objective To explore MR features of soft tissue hemangiomas.Methods The size,margin,morphology and signal pattern of soft tissue hemangiomas on MRI proved pathologically in 16 cases were retrospectively analyzed.Results Of the 16 cases,there were 9 cases of angiocavernoma(2.0~5.0 cm in size),the lesions had defined border,homogeneous high signal intensity on T2WI.5 cases of tramusoular hemangioma,the tumors preseneted as irregular mass with mixed signal intensity and mainly composed of high signal intensity on T2WI.2 cases of pampiniform angioma,tortuous dilation of blood vessel and muscular atrophy were its MRI features.Conclusion Soft tissue hemangioma can usually be diagnosed correctly according to MRI characteristics and clinical data.
