The authors discuss four cases of gastric leiomyosarcoma explored by various imaging techniques (barium examinations, ultrasound, CT scans). Barium examinations were normal in two cases, abnormal but insufficient for diagnosis in one, and sufficient to allow topographic diagnosis in one. Ultrasonography gave abnormal findings insufficient for diagnosis in two cases and allowed topographic diagnosis in the other two cases. CT scans were abnormal but insufficient for diagnosis in one case, allowed topographic diagnosis in 3 cases, and in two of the cases permitted initial diagnosis of a connective tissue malignancy. Due to the frequently subserosal nature of leiomyosarcoma of the stomach and of the digestive tract in general, analysis by CT in mandatory. Analysis of tumor relations with the spleen, the left kidney and the pancreas is facilitated by ultrasonography.
作者讨论了4例胃平滑肌肉瘤病例，这些病例采用了多种成像技术（钡剂检查、超声、CT扫描）进行检查。钡剂检查中，2例结果正常，1例异常但不足以用于诊断，1例足以进行定位诊断。超声检查发现2例异常但不足以用于诊断，另外2例可进行定位诊断。CT扫描中，1例异常但不足以用于诊断，3例可进行定位诊断，其中2例可初步诊断为结缔组织恶性肿瘤。由于胃平滑肌肉瘤以及一般消化道平滑肌肉瘤常位于浆膜下，因此必须进行CT分析。超声检查有助于分析肿瘤与脾脏、左肾及胰腺的关系。
