摘要
目的 :探讨胃肠道平滑肌肉瘤的X线和CT表现 ,以提高对该病的诊断能力。方法 :回顾分析经手术病理证实的 2 0例胃肠道平滑肌肉瘤的X线表现及其中 11例胃平滑肌肉瘤的CT表现。结果 :均为单发病例 ,X线片上腔内型 4例 ,表现为圆形、半圆形充盈缺损或软组织肿块 ,肿瘤中心出现不规则的龛影。腔外型 6例 ,为胃肠轮廓外压性改变及较大龛影或肠腔与肿瘤之间隧道样改变 ,腔内外型 10例 ,兼有上述 2型表现。 11例胃平滑肌肉瘤CT上表现为直径 6～2 0cm分叶状肿块 ,密度不均匀且有不均匀强化 ,有邻近器官侵犯。结论 :胃肠造影检查和CT扫描密切结合 。
Objective:To study X-ray and CT features of gastrointestinal leiomyosarcoma in order to improve their diagnostic ability.Methods:X-ray feature of gastrointestinal leiomyosarcoma in 20 cases confirmed by operation and pathology, and CT feature of gastric leiomyosarcoma in 11 of 20 cases were analyzed retrospectively.Results:Single gastrointestinal leiomyosarcoma in all cases was found,and X-ray feature was as following:there was a filling defect of round or oval shape or a mass in intraluminal type (4 cases),there was a large,irregular ulcerative crater in the center of tumor.In the extraluminal type (6 cases),the gastrointestinal contour showed compression,deformity,giant crater,and a “tunnel” located between gastrointestine lumen and tumor.The mixed type (10 cases) had appearances of the above two types.In 11 cases of gastric leiomyosarcoma,CT demonstrated large lobulated tumor mass(diameter 6～20cm) with heterogenous density and non-homogenous enhancement.There was also invasion of adjucent organs.Conclusions:Gastrointestinal contrast examination combined with CT scan is very helpful to improve the diagnostic ability for gastrointestinal leiomyosarcoma.
