ABSTRACT
A 14-year-old boy presenting headache crisis, sweating and palpitation was observed. On ultrasound scan, a 3 × 2.5 cm hypoechoic mass, highly vascularized, was observed arising from the left bladder wall. Magnetic resonance imaging confirmed the mass situated close to the ureteral orifice, with intense peripheral enhancement and a central non-enhanced portion. Left partial cystectomy was performed. Large clear cells, presenting cytoplasmatic granules positive for S100 and chromogranin, were observed at histology. Bladder paraganglioma derives from chromaffin tissue of the sympathic system and it is uncommon in children. The estimated prevalence is very low (0.06% of bladder tumors). Symptomatology is related to the catecholamine production. In pediatrics, prognosis is usually good but long-term follow-up is required.
