Abstract: Extraadrenal paragangliomas are tumors composed of neuroendocrine-derived, catecholamine-secreting chromaffin cells inducing hypertension, palpitations, and diaphoresis [1]. Although extraadrenal paragangliomas are found in a variety of anatomic sites that normally host paraganglia—from the carotid body to the abdominal paraaortic region—the bladder is an uncommon location for paragangliomas. Bladder paragangliomas represent approximately 6% of extraadrenal paragangliomas and only 0.05% of all bladder tumors [2,3]. We present a rare case of primary paraganglioma affecting the bladder dome.
