小肠间质肿瘤钡餐造影与CT扫描对照分析

Stromal Tumors of Small Intestine: A Comparative Study of Barium Meal and CT Findings

目的 评价钡餐造影和CT扫描诊断小肠间质肿瘤的价值。资料与方法 分析 11例经手术病理证实的小肠间质肿瘤的影像学资料。结果 良性间质肿瘤 4例 ,恶性间质肿瘤 7例 ,以空肠最多见 (6 / 11)。钡餐造影主要表现为黏膜变平 ,环状皱襞消失或破坏 ,肠腔偏侧性狭窄 ,出现钡斑或窦道样改变 ,腔内充盈缺损。CT检查均确诊为小肠肿瘤 ,主要征象为腔外不规则肿块 ,肿块内多灶性低密度坏死区。结论 小肠间质肿瘤并非罕见 ,对临床疑为此症者应首选胃肠钡剂造影 ,CT是明确诊断的主要影像检查技术 ,并可为手术治疗进一步明确病变范围。

Objective To evaluate the barium meal radiography and CT scans in diagnosing stromal tumors of small intestine.Materials and Methods Imaging findings, including barium meal radiography and CT scans, in 11 patients with pathologically proved stromal tumors of small intestine were retrospectively analyzed.Results The lesion was benign in 4 and malignant in 7 patients, and in 6 cases the lesion was located in the jejunum. On barium meal radiographs, flattened mucosal fold, disappearance and destruction of the circular folds, eccentric lumen stenosis, barium fleck or fistula shadow within the tumor and filling defect were seen. On CT scans, the main manifestation was an extraluminal mass with multiple necrosis areas of low density.Conclusion The stromal tumors of small intestine is not rare. For all suspected patients, gastrointestinal barium meal examination should be performed. CT is the main imaging technique to confirm the diagnosis and to demonstrate the lesion's extent which is very important for the surgical management.
