This report describes a 33-year-old woman who presented with renovascular hypertension secondary to retroperitoneal fibrosis, associated with a carcinoid tumour with widespread metastases. Although the association is rare, it is important to consider carcinoid tumour as a cause of idiopathic retroperitoneal fibrosis, even in the absence of the carcinoid syndrome.
