Abstract:
Objective To investigate the difference of CT features of gastrointestinal stromal tumors(GIST),neurogenic tumors,and leiomyomas in stomach.Methods A retrospective analysis was performed on clinical and CT features from 312 cases of GIST,21 cases of neurogenic tumors,and 35 cases of leiomyomas in stomach.Results GIST were most commonly found in the body of stomach and exhibited large tumor sizes and late onset.CT showed GIST predominantly showed intraluminal and mixed growth pattern with irregular or round shapes and uneven density,and cystic degeneration and calcification were frequently observed.The CT values of GIST in the arterial phase and the degree of arterial enhancement were higher,with light to moderate arterial phase enhancement and moderate to marked venous phase enhancement.Gastric leiomyomas had smaller tumor sizes and presented mainly in the cardia,gastric fundus,and lesser curvature of gastric body.CT showed the intraluminal growth pattern,primarily in round shapes with uniform density,lower incidence of cystic degeneration and calcification,both the arterial and venous phase CT values and the extent of enhancement in these phases were lower,showed no or slight enhancement during the arterial phase and light to moderate enhancement during the venous phase.Gastric neurogenic tumors were predominantly located in the gastric body and antrum.CT showed the tumors demonstrated extraluminal and mixed growth patterns,most with oval-shaped appearace,uniform density and the venous phase CT values and the degree of enhancement were higher,with light to moderate arterial enhancement and moderate to marked venous enhancement.Conclusion GIST,neurogenic tumors,and leiomyomas in stomach can be differentiated based on their distinct CT features.Accurate recognition of these features aids in the differential diagnosis of these kinds of tumors.
