1. While adenocarcinoma is the most common type of gastric cancer, lymphoma, gastrointestinal stromal tumors, neuroendocrine tumors, and metastases should also be considered when evaluating an unknown gastric lesion. 2. Awareness of the distinctive CT, MR, and PET features of the less common tumors, such as the commonly large size, cystic contents, and intraluminal and extraluminal components of GISTs, can prompt the radiologist to raise them as differential diagnostic considerations. 3. Radiologists can adapt their imaging strategies to detect the differing patterns of regional and systemic spread among these entities.  

1. Review of the most common types of malignancies involving the stomach, including adenocarcinoma, lymphoma, GIST, gastric neuroendocrine tumors, and metastases. Benign lesions such as leiomyomas and lipomas will also be discussed. 2. Multimodality review of the imaging features characteristic of these neoplasms. 3. Review of prognosis and local, regional and metastatic spread of these entities, with a focus on optimal imaging follow up. 4. Discuss the different treatment strategies for primary gastric malignancies. 5. Demonstrate important issues in the imaging of treatment response and treatment complications associated with these entities.
