Abstract: Objective To investigate multi-slice spiral CT manifestations and its diagnostic value of extragastrointestinal stromal tumor(EGIST).Methods CT data in 19 patients with EGIST proved pathologically were retrospectively reviewed.Results Of the 19 cases,the lesions located in reteoperitoneum in 8 cases,adrenal,greater omentum,omentum and mesentery in one case respectively,mesentery in 4 cases,and abdominal cavity in 4 cases.2 cases were benign,4 cases were potential malignant,and 13 cases were malignant.The size of tumors ranged 4.1～35 cm.The tumors were round or oval in 5 cases,lobulated in 5 cases and irregular in 9 cases.The tumors in 4 cases were uniform density on plain CT scans,1 case of uniform and moderate enhancement,1 case of non-uniform enhancement,2 cases of apparent enhancement as ring on contrast-enhanced CT scans;15 cases showed unhomogeneous density,on contrast-enhanced scans,moderate or remarkable enhancement was seen in the parenchyma of the tumor,while no enhancement was revealed in the necrosis and cystic areas of the tumors.Conclusion EGIST have certain imaging characteristics and MSCT was valuable in diagnosing and differential diagnosing EGIST.
