Abstract
IntroductionPheochromocytoma (PHEO) is a rare catecholamine-producing tumour arising from chromaffin cells in the sympatho-adrenal system, and can present as asymptomatic adrenal incidentaloma (AI).PatientWe describe the case of a 61-year-old woman with a right adrenal mass incidentally discovered, who was biochemically characterized with subclinical hypercortisolism (SH). The patient was scheduled for adrenalectomy because of increasing seizure of the right adrenal gland with a haemorrhagic and focal pseudocystic appearance macroscopically, incidental histological and immunohistochemical PHEO, and micronodular cortico-adrenal hyperplasia.DiscussionThis report describes a rare case of incidental non-functioning PHEO coexisting with corticomedullary hyperplasia and SH.LEARNING POINTSRare presentation of coexisting common (adrenal incidentaloma and subclinical Cushing’s syndrome) and uncommon (pheochromocytoma) endocrinological conditions.
