title: Exophytic adenocarcinoma of the stomach: computed tomography and ultrasonography features with emphasis on differentiation from a malignant gastrointestinal stromal tumor.
abstract: The purpose of this study was to assess the computed tomography (CT) and ultrasonography (US) findings from cases of exophytic adenocarcinoma of the stomach (EAS) and to determine their value in distinguishing between an EAS and a malignant gastrointestinal stromal tumor (MST). US and CT findings of EAS and MST were assessed retrospectively. Antral location, thickening of the gastric wall adjacent to an exogastric mass, lymph node enlargement, and discordant images between US and CT are typical of EAS cases and allow distinction between cases of EAS and MST.
