Bladder paraganglioma is a rare neuroendocrine tumor arising from extra-adrenal chromaffin tissue and accounting for less than 0.1% of all bladder tumors, with non-functional forms often posing diagnostic challenges due to the absence of specific symptoms. We report the case of a 53-year-old male patient with no significant medical history who presented with febrile right iliac fossa pain and vomiting, without urinary or adrenergic manifestations. Abdominal ultrasound revealed acute appendicitis associated with an incidental bladder mass. Following appendectomy, the patient was referred for further evaluation. Clinical examination was unremarkable, and transurethral resection of the bladder tumor was performed without intraoperative hemodynamic instability. Histopathological and immunohistochemical analysis confirmed the diagnosis of bladder paraganglioma. Postoperative imaging showed no additional lesions, and biochemical evaluation for catecholamine secretion was within normal limits. Partial cystectomy was recommended but declined by the patient.
