Abstract:
Objective To analyze imaging of gastrointestinal stromal tumors(GIST),and to compare their imaging features with operational and pathological findings.Methods Clinical,imaging,and pathological data of 20 patients with GIST were collected.Results Imaging findings were endophytic or exophytic tumors with heterogeneous density or signal intensity,corresponding to hemorrhage,necrosis,and cystic changes.Imaging was correct for the location of the lesion in 11 of 16 primary GIST and 4 cases of relapsed tumors.Preoperational CT did not detect mesenteric,peritoneal,and omental metastasis in 5 cases. Hepatic metastases detected at CT (3 cases )were identified by operational findings.Conclusions GIST has some imaging features.CT is a useful tool in detecting and characterizating of lesions rather than detecting mesenteric,peritoneal,and omental metastasis.
