Abstract
Paragangliomas and pheochromocytomas are rare catecholamine secreting neoplasms that arise in the extra-adrenal autonomic paraganglia and adrenal medulla, respectively. Although typically presenting with paroxysms of headaches, palpitations, diaphoresis and hypertension, a broad spectrum of clinical manifestations may occur. Diagnosis relies on biochemical studies followed by adequate imaging investigation. Cross sectional morphological and functional imaging modalities have improved diagnostic accuracy and are crucial in the surgical planning. The authors report on a case of a 64-year-old female that presented with severe hypertension, palpitations and fatigue as the manifestations of a catecholamine secreting neoplasm. Abdominal contrast enhanced computer tomography revealed a right sided 78 mm adrenal medullary tumor suggestive of a pheochromocytoma. Standard therapeutical strategies were initially unsuccessful, and additional investigation and therapy were required to cure the patient. The challenges faced by the multidisciplinary team in the pre-operative evaluation, medical management and surgical treatment are reported.
