Abstract
The diagnosis and investigation of phaeochromocytoma was reviewed in three patients presenting to the paediatric renal centre with malignant hypertension. The initial diagnosis was made using urinary 4-hydroxy-3-methoxymandelic acid (VMA) and plasma adrenaline and non-adrenaline estimations. Our experience of the localization of phaeochromocytoma with ultrasound, 131I-meta-iodobenzylguanidine (MIBG) and venous sampling was discussed and we have reappraised our approach to the localization of these tumours.
