title: Gastrointestinal carcinoid tumors in rare locations: imaging findings.
abstract: In this article, we present radiological findings in three patients with mesenteric, gastric, and rectal carcinoid tumors. More than 90% of the carcinoid tumors arise in the gastrointestinal system (GIS). They comprise 2% of all GIS tumors and are usually located in the small intestine and the appendix. On the other hand, gastric, rectal, and mesenteric carcinoids are rare. Better knowledge of radiological features of carcinoid tumors in rare locations will prevent diagnostic delays and development of carcinoid syndrome.
