1. Nuclear medicine imaging and treatment in pheochromocytoma, paraganglioma, and role of the new tracer 11C-hydroxy ephedrine in diabetes mellitus
Abstract : Carbon-11 hydroxy ephedrine (11C-HED) is a norepinephrine analog which binds to the norepinephrine receptor present in adrenal medulla, lung, liver and pancreas. 11C-HED-positron emission tomography with concomitant computed tomography (PET/CT) can image these organs. READ MORE

2. Genetic Alterations in Pheochromocytoma and Paraganglioma
Abstract : Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from neural crest-derived cells of the adrenal medulla and the extra-adrenal paraganglia. They cause hypertension due to an abnormally high production of catecholamines (mainly adrenaline and noradrenaline), with symptoms including recurrent episodes of headache, palpitations and sweating, and an increased risk of cardiovascular disease.

3. Incidentally discovered adrenal tumours, adrenal metastases and pheochromocytomas - Clinical and epidemiological aspects
Abstract : With increasing use of high resolution radiological imaging incidentally discovered adrenal tumours (adrenal incidentalomas, AI) have become a common clinical problem. The aim of work-up and follow-up of patients with AI is to detect malignant (primary or metastatic) and/or hormone-producing tumours. READ MORE

4. Pheochromocytoma and abdominal paraganglioma : clinical and genetic aspects
Abstract : Pheochromocytomas and abdominal paragangliomas are rare catecholamine producing tumours arising from sympathoadrenal paraganglia located within and outside of the adrenal medulla, respectively. The great majority of tumours are benign and cured by surgery. READ MORE

5. Genetic and molecular background of pheochromocytoma and paraganglioma
Abstract : Pheochromocytomas (PCC) and abdominal paragangliomas (PGL), collectively denoted PPGL, are neuroendocrine tumors (NET) with a highly diverse genetic and molecular etiology, arisen in the adrenal medulla and abdominal paraganglia respectively. The tumors often cause cardiovascular symptoms due to the high production of catecholamines, and malignancy occurs in 10% of the PCCs and 30% of the PGLs. READ MORE
