Abstract：Objective: To investigate the CT features of intestinal stromal tumors and its diagnostic value. Materials and Methods: The CT imaging data of 15 cases with intestinal stromal tumors confirmed by operation and pathology were analyzed retrospectively, the gross pathologic findings of the tumors were compared with the manifestations of CT. Results: Among the 15 cases, 5 cases located at duodenum, 4 cases at jejunum, 3 cases at ileum, 2 cases at colon, 1 case at multisegments of intestine and colon. All cases presented as celiac or pelvic soft tissue tumors with diameter of 2.7~24cm, 5 cases were less than 5cm and 2 cases of them were benign, 10 cases were larger than 5cm which were all malignant; Seven cases presented with a irregular margin; Twelve cases showed heterogeneous density on plain scan with slightly and moderately heterogeneous enhancement; Two cases had liver metastasis, 2 cases recurred; Four cases were preoperatively misdiagnosed, 6 cases were localized precisely and 5 roughly. Conclusion: Although precisely preoperative localization of intestinal stromal tumors is difficult, CT findings of tumor features and the relationship with adjacent tissues or organs can be of great help and also for evaluation of malignant or benign lesions.
