Case: Eosinophilic cystitis presenting as a bladder mass in an 11-year-old girl.

We report the case of an 11-year-old girl who presented with acute urinary retention and microscopic hematuria. Pelvic imaging revealed a bladder mass for which sarcoma was initially suspected. Surgical biopsies revealed a massive eosinophilic infiltration of the submucosa confirming a diagnosis of eosinophilic cystitis. Clinical evolution was favourable without treatment. Eosinophilic cystitis prognosis is usually benign, but rare severe complications, such as complete bladder fibrosis requiring bladder augmentation or cystectomy, may occur.
