摘　　要：目的　探讨子宫阔韧带肌瘤的CT诊断价值。方法　收集 2 1例子宫阔韧带肌瘤CT资料 ,进行回顾性分析 ,所有病例均经手术病理证实。结果　 2 1例均在盆腔内、子宫外显示肿块 ,CT表现 :实质性肿块 19例 ,边界清楚光整 16例 ,不甚清楚 3例 ,密度均匀 6例 ,平扫时与子宫肌密度相当 ,增强扫描呈明显强化 ,与子宫肌强化基本同步 ,不均匀 13例 ,其强化程度低于子宫肌 (约相差 10～ 2 0HU) ,瘤内变性、坏死或液化区不明显强化或不强化 ;囊实性 2例 ;肿块位置较固定 ,大多在宫旁匍匐生长 ,与子宫位置密切相关 ,其最大径层面与子宫体中心层面基本保持一致 ;形态各异 ,呈条块状、哑铃分叶状及扁圆烧饼状共 15例 ,呈圆形、椭圆形6例。结论　子宫旁呈条块、哑铃分叶状及扁圆烧饼状的实质性或实质性为主的肿块是本病较为可靠的CT征象 。Objective To investigate the CT diagnostic value of broad ligament leiomyoma.Methods CT appearances of 21 cases with broad ligament leiomyoma confirmed by operation and pathology were analyzed retrospectively.Results CT showed that the tumors were pelvic and extrauterine masses in all cases,the tumors were solid in 19 cases and was cystic-solid in one case. The tumors had clear border in 16 cases and unclear border in 3 cases. The density of tumor in 6 cases were homogeneous, which was similar to that of myometrium on precontrast scanning. There was obviously uptake on postcontrast enhancement, as in myometrium. In heterogeneous tumors, low density areas of light flakes or streaks were observed, and the density of tumor solid part was somewhat lower than that of the uterus muscles on postcontrast enhancement. The tumors grew near the uterus. The shape of tumors appeared multitudinous, which was multilobular or irregular in 11 cases, flat round in 4 cases, and round or elliptic in 6 cases. Conclusion CT is a useful tool in diagnosis of the broad ligament leiomyoma.
