Abstract
Pheochromocytoma is a tumor that originates from the chromaffin cells of the adrenal medulla and is responsible for the production of catecholamines. However, when it occurs outside the adrenal glands, it is called a paraganglioma and accounts for 10%-15% of cases. In this report, we present the case of a 27-year-old male patient with a history of hypertension, who presented hematuria and dizziness on urination with a diagnosis of bladder paraganglioma. Contrast-enhanced computed tomography revealed the presence of a bladder tumor. Bladder paraganglioma is a rare condition, and understanding possible imaging findings is crucial to raising suspicion of this diagnosis and expanding our knowledge of this rare disease.
