Evaluation of CT Scan and Barium Radiography of Upper Digestive Tract in Diagnosing Gastric Schwannoma / 实用放射学杂志

ABSTRACT

Objective To study the value of CT and barium radiograpy in diagnosis of gastric schwannoma.Methods A retrospectiveanalysis was made on imaging of 8 patients with pathologically approved gastric schwannoma.Plain abdominal CT scan was performed in all patients, additional enhanced CT scan was carried out in 6 cases and barium radiography of upper digestive tract was carried out in 5 cases. Results The lesions localized in fundus ventriculi in 2 cases, curvatura ventriculi minor in 4 cases and pars pylorica in 2 cases. Three main types were seen: localized mass type (n=4), localized thickening of gastric paries type (n=2) and huge mass type (n=2).Conclusion In comparison with barium radiography of upper digestive tract, CT can accurately demonstrate the shape, the location and internal structure of lesions.Three main patterns of this lesion also can be showed clearly by CT scans and suggestive diagnosis can be made in some patients combined with barium radiography of upper digestive tract images.
