title: Radiology of carcinoid tumours of the small intestine.
abstract: Carcinoid tumors of the small intestine are particularly known in the literature for their hormonal activity and for the carcinoid syndrome caused by the serotonin they produce. The radiological symptoms are based, not only on changes caused by the tumour itself but also on changes induced by hormonal products in the intestinal wall and mesentery. The classical excentric intramural defect in the contrast column is therefore often accompanied by swollen mucosal folds, swelling of the intestinal wall and evidence of mesenteric retraction.
