Abstract:
A 45-year-old patient presented with a history of recurrent abdominal pain of unknown origin. The CT scan of the abdomen demonstrated a thickened mesenteric root and a segmental ileus of the jejunum. Laparotomy revealed a neuroendocrine tumour of the small bowel. Such tumours are rare causes of recurrent abdominal pain. Especially when the CT scan of the abdomen reveals mesenteric abnormalities (desmoplastic reaction) and/or a segmental ileus, a neuroendocrine tumour of the small bowel should be considered. The therapy of choice is resection of the tumour followed by systemic therapy including somatostain analogues and chemotherapy in the case of a hormone secreting tumour or metastases.
