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.
小肠类癌肿瘤在文献中因其激素活性以及由其所产生的血清素引起的类癌综合征而特别为人所知。放射学症状不仅基于肿瘤本身所引起的变化，还基于肠壁和肠系膜中激素产物所诱发的变化。因此，造影剂柱中典型的偏心壁内缺损常常伴有黏膜皱襞肿胀、肠壁肿胀以及肠系膜退缩的迹象。
