Paragangliomas, as well as pheochromocytomas, are neuroendocrine tumours, which often secrete catecholamines. This hypersecretion causes symptoms that are often difficult to control. Pheochromocytomas originate in the medulla of the adrenal glands and make up 80-85% of cases, whereas paragangliomas originate extra-adrenally and make up 15-20% of cases. Paragangliomas are rare tumours, and altho...

BACKGROUND Isolated retroperitoneal cystic masses are uncommon with an estimated incidence of 1/5750 to 1/250,000. The majority present with size related symptoms, complications, or a mass. Approximately a third of patients are asymptomatic and are diagnosed incidentally. Aetiologies of retroperitoneal cystic masses (RPC) include mesenteric, omental, splenic and enteric duplication cysts. Neopl...
