This report describes a 65-year-old woman with a history of phaeochromocytoma and a right-sided adrenal mass. Biochemical findings and localisation procedures suggested an extra-adrenal phaeochromocytoma which was confirmed by surgery. We conclude that an extra-adrenal tumour should be considered in the evaluation of a phaeochromocytoma even if an adrenal tumour is present-the latter may represent an `incidental` adrenal mass.
