A Rare Cause of Macroscopic Hematuria: Primary Bladder Paraganglioma: A Case Report on Clinical, Imaging, and Treatment Approaches

Pheochromocytomas are tumors originating from the chromaffin cells of the adrenal medulla that can cause the release of catecholamines. Pheochromocytomas located outside the adrenal glands are referred to as paragangliomas and account for 10-15% of all pheochromocytoma cases. This case report presents a 30-year- old female patient diagnosed with primary bladder paraganglioma who presented to our clinic with the sole complaint of hematuria. After the detection of a mass in the bladder via abdominopelvic ultrasound to investigate the etiology of hematuria, further advanced investigations and histopathological examinations led to the diagnosis of the exceedingly rare primary bladder paraganglioma. By examining this disease clinically, radiologically, and histopathologically, we aim to expand our knowledge of this condition.
