摘要
目的 探讨四肢软组织血管瘤的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四肢软组织血管瘤 18例 ,分析其大小、边缘、形态及信号特征。结果 18例中 ,海绵状血管瘤 8例 ,肿瘤直径 1 0～ 4 0cm ,边界清 ,多呈均匀性高信号 ,瘤周有低信号环。肌间血管瘤 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 3例 ,血管迂曲扩张和肌肉萎缩是其特征性MRI表现。静脉瘤 2例 ,静脉粗大、壁厚 ,无供血动脉。结论 四肢软组织血管瘤MRI表现有一定的特征性 ,结合临床 。
Objective To explore the MRI features of soft tissue hemangiomas. Methods The size, margin, morphology and signal pattern of the lesions in MRI findings in 18 patients with soft tissue hemangiomas proved pathologically were retrospectively analyzed. Results Of the 18 cases, there were 8 cases of angiocavernoma (1 0-4 0 cm in size) with clear border, homogeneous high signal in the lesion and low signal ring on the border, 5 cases of intramuscular hemangioma, presented as irregular mass with mixed signals mainly composed of high signal on T2WI, 3 cases of angioma arteriale racemosu with tortuous dilation of blood vessel and amyotrophy as its MRI feature, and 2 cases of venous angioma with thick wall of vein but without supplying arteries. Conclusion Soft tissue hemangioma can usually be diagnosed correctly according to MRI characteristics and clinical data.
