ABSTRACT

Objective To evaluate spiral CT diagnosis of gastrointestinal stromal tumors (GIST).Methods The CT findings and clinicopathological data of 32 GIST cases were retrospectively analyzed. Results Of the 32 GIST cases, 1 located in the esophagus, 22 in the stomach, 1 in the mesentery, 6 in the small intestine and 2 in the colon. There were 4 benign and 28 malignant cases. Expression of CD117 and CD34 was 75% and 81% respectively. The lesions were exogenous in 56% cases. The average size of the benign and malignant masses was 4. 75cm and 6.78cm respectively. Conclusions Spiral CT could provide important information for the diagnosis and localization of GIST, but the final diagnosis still relies on pathology.
