[Ileocoecal intussusception of the terminal ileum caused by a carcinoid tumor].

Intussusception of the intestine is a frequent reason for intestinal obstruction in infants; the course is acute but the causes are often not recognizable. In adults intussusception is the cause for bowel obstruction in only 1% of cases. The course is subacute and in over 90% a benign or malignant process in this part of the intestine is found. We report the case of a 45-year-old male with abdominal discomfort, increasing over weeks. The preoperative ultrasonography and computed tomography of the abdomen revealed the typical finding of ileocoecal intussusception. An ileocoecal resection was performed. The histopathological workup showed a small carcinoid tumour of the terminal ileum.
