Bladder pheochromocytoma: case presentation and the use of OctreoScan for localization of extra-adrenal tumor sites in a pediatric patient

An eleven year old boy presented with headaches and dizziness associated to micturition. On radiologic imaging, he was found with a bladder mass. The biochemical work up was suggestive of pheochromocytoma. An OctreoScan (111In-pentreotide) was used to rule out metastatic extension or other extra-adrenal locations of the pheochromocytoma. OctreoScan data correlated well with other radiologic studies, operative findings and with the final diagnosis, validating its use on pediatric patients.
