Polypoid Cystitis in a 3‑Year‑Old Child: A Rare Occurrence

Abstract

Polypoid cystitis is a rare, benign, reactive, exophytic urinary bladder mucosal lesion whose etiology has been attributed to chronic non‑specific injury to bladder mucosa. It is most commonly seen in patients with indwelling catheter. It is a recognized mimic of bladder neoplasms. The findings at imaging studies are not well known. We report a case in a three years old child who presented with a severe form of the disease on a background of resistant E. coli infection. The patient was treated with antibiotics, and surgical resection of the mass and patient has been on follow‑up since. The present case is notable in that it occurred in a child with no known predisposing factor except for history suggestive of recurrent bacterial urinary tract infection.
