Excerpt

Phaeochromocytoma and sympathetic paragangliomas are rare catecholamine-producing tumours arising from the adrenal medulla or extra-adrenal sympathetic paraganglia. Phaeochromocytoma was labelled as a disease with ‘multiple faces’ due to its highly variable clinical presentation [1]. Some patients may be asymptomatic, whereas in others, phaeochromocytomas are associated with major cardiovascular manifestations [2]. In addition to hypertension, catecholamine excess can be at the origin of cardiac arrhythmias, myocardial infarction, haemodynamic collapse, heart failure, pulmonary oedema and cardiac arrest [3].
