Phaeochromocytoma of the urinary bladder localized by selective venous sampling and computed tomography

Clinical and biochemical evidence of a catecholamine-secreting tumour was documented in a 19-year-old female presenting with malignant hypertension. The tumour was successfully localized to the pelvis by means of plasma noradrenaline assay from multiple sites, after previous attempts at localization had failed. Subsequently, computed tomographic (CT) scan allowed correct pre-operative localization to the urinary bladder.
