Carcinoid tumors of the stomach: a clinical and radiographic study.
OBJECTIVE
Our purpose is to describe associated and coexistent diseases of gastric carcinoid tumors, the unique biologic behavior of these tumors, the appearance of these tumors on fluoroscopic and CT images, and the radiologic management of these neoplasms.


CONCLUSIONS
First, multiple gastric carcinoid tumors are associated with enterochromaffin-like cell hyperplasia, chronic atrophic gastritis, and pernicious anemia and have a low risk of malignancy. Second, solitary gastric carcinoid tumors, or gastric carcinoid tumors associated with multiple endocrine neoplasia-type I (MEN-I) and Zollinger-Ellison syndrome, have a higher potential for metastatic disease. Third, the radiologic appearance and management of these tumors depend on the clinical background of the patient.
