| 摘 要： | 目的探讨四肢软组织横纹肌肉瘤的影像学特征及提高对其诊断水平。资料与方法回顾性分析6例经病理证实的四肢横纹肌肉瘤的影像学表现。5例行MRI增强扫描,2例行CT增强扫描。结果 1例发生于上肢,5例发生于下肢,5例边界较清晰。在MRI上与肌肉相比,T1WI上以等信号为主,2例内部可见线条状留空信号,T2WI呈不均匀高信号,T2WI抑脂序列上呈较均匀的高信号,注射Gd-DTPA增强扫描,3例病灶呈不均匀明显强化,2例病灶强化较均匀;4例可见明显包膜形成,瘤周未见水肿。2例在CT检查中显示病变与肌肉相比在平扫可见等、低密度成分,以前者为主,1例相邻骨质可见溶骨性破坏且瘤内可见散在不规则钙化影,增强扫描轻度及明显强化各1例。结论四肢软组织横纹肌肉瘤无明显影像学特征,若在检查中发现四肢软组织肿块且强化明显时,横纹肌肉瘤应纳入鉴别诊断中,最终确诊依靠病理检查。
