目的 提高消化道平滑肌肿瘤的临床X线诊断水平。方法 回顾分析经手术和病理证实的 40例消化道平滑肌肿瘤的临床和X线检查资料。结果 食管 15例 ,其中平滑肌瘤 14例 ,平滑肌肉瘤 1例。主要X线表现 :管腔内充盈缺损、粘膜皱襞展平、管腔增宽、管旁肿块。胃肠 2 5例 ,平滑肌瘤 6例 ,平滑肌母细胞瘤 7例 ,平滑肌肉瘤 12例。X线表现取决于肿瘤的生长方式。可分为 :腔内型 ,腔外型 ,腔内外型及肌间型。前三者主要表现 :①腔内充盈缺损或软组织块影 ;②肿瘤中央龛影 ;③肿瘤坏死囊变 ;④胃肠本身及邻近器官受压移位 ;⑤偶见肿瘤钙化。肌间型病变较小 ,X线检查不易发现。结论 依照上述X线表现 ,术前可以作出正确诊断。
Objective To improve the clinical X-ray diagnosis of gastrointestinal smooth muscle tumors. Methods The clinical and X-ray findings of 40 cases of gastrointestinal smooth muscle tumors confirmed by surgery and pathology were retrospectively analyzed. Results The esophagus in 15 cases, including 14 cases of leiomyoma, 1 case of leiomyosarcoma. The main X-ray manifestations: filling the defect within the lumen, mucosal folds flattening, lumen widening, next to the tube mass. 25 cases of gastrointestinal, leiomyoma in 6 cases, 7 cases of smooth muscle cell tumor, leiomyosarcoma in 12 cases. X-ray performance depends on the growth of the tumor. Can be divided into: cavity type, cavity type, cavity type and intermuscular type. The first three main manifestations: ① cavity filling defect or soft tissue mass shadow; ② central niche tumor; ③ tumor necrosis cystic disorder; ④ gastrointestinal itself and adjacent organs pressure shift; ⑤ occasional tumor calcification. Myenteric lesion smaller, X-ray examination is not easy to find. Conclusion According to the above X-ray findings, preoperative diagnosis can be made correctly.
