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.
