Paragangliomas are the neuroendocrine tumors which arise from the chromaffin cell. Tumors arising from the adrenal medulla are known as pheochromocytomas, while others originating from the extra-adrenal site are known as extra-adrenal paragangliomas. Paraganglioma can be multifocal which can arise synchronously or metachronously. Paragangliomas are less functionally active than the pheochromocytomas; they secrete noradrenaline and rarely dopamine, while adrenal pheochromocytomas secrete adrenaline or nor-adrenaline. Nonfunctional multifocal paragangliomas are very rare. We report a case of a 45-year-old female with multifocal nonfunctional paragangliomas of the retroperitoneum and urinarybladder which were surgically removed, and the diagnosis was confirmed on histopathology.
