Carcinoid syndrome. Radiology.

The carcinoid syndrome is usually produced by an ileal carcinoid tumour that has metastasized to the liver but can also be caused by similar tumours in many other organs. These neoplasms create a variety of radiological appearances which are often characteristic. In recent years percutaneous embolization of hepatic carcinoid metastases has been successfully employed as part of the treatment of the syndrome.
