Subclinical phaeochromocytoma: a diagnostic and management challenge

Abstract

There is a paradigm shift in the detection of phaeochromocytomas with more being identified as adrenal 'incidentalomas'. While majority of these individuals are asymptomatic, they are nevertheless at risk of subtle cardiovascular dysfunction and phaeochromocytoma crises. Therefore, early resection of phaeochromocytomas, even if subclinical, is recommended. However, the perioperative management can be challenging as the normotension can limit the initiation and titration of alpha-blockade. We present a man in his 60s with a subclinical phaeochromocytoma, discuss the evaluation of an incidentally discovered adrenal nodule, as well as the practical considerations in the perioperative management.
