     [摘要] 目的：探讨腹部平滑肌肉瘤的CT表现特点及其诊断价值。方法：回顾性分析经手术或病理证实23例平滑肌肉瘤的CT表现，术前均行CT平扫，大部分行增强扫描。结果：平滑肌肉瘤常单发,大小不一,行态多变,发生于胃12例,结肠5例,小肠4例,肠系膜2例,平均直径为3.8 cm~6.5 cm,大多边缘清晰,伴肠管及肠系膜血管移位,平扫表现为等密度,稍高密度14例,周边等密度,中央低密度6例,混杂密度2例，增强后明显强化12例,边缘明显强化7例,不均匀强化4例。结论：CT对腹部平滑肌肉瘤定位准确,对肿瘤良恶性判断亦很有价值，但CT表现无特异性，确诊仍有赖于病理学检查。

    Abstract：Objective To discuss CT features of Leiomyosarcoma on abdomen and to evaluate CT scanning in its diagnosis.Methods Both plain and enhanced CT findings in 23 cases with pathologicallyproved LSA were retrospectively analyzed.Results Leiomyosarcoma on Abdomen usually solitary and welldefined LSA from the stomach (n=12),colon(n=5),ileum and jejunum (n=4),mesentery (n=2),with an average diameter of 6.5cm.The adjacent intestinal loop was deviated due to the space occupying effect of the lesion.On plain CT scans
