A rare presentation of eosinophilic cystitis in paediatric urology

Abstract

Eosinophilic cystitis (EC) is a rare inflammatory condition of the urinary bladder. It is extremely rare in childhood and may present with haematuria, lower abdominal mass or recurrent urinary tract infections. We present the case of a 5-year-old girl with recurrent, painless visible haematuria. Ultrasound showed a bladder mass and left hydronephrosis. Cystoscopy and bladder biopsy confirmed the diagnosis. The patient was successfully managed with oral treatment. In the case of EC, cystoscopy and bladder biopsy is key for diagnosis. Conservative management of unilateral hydronephrosis in EC is appropriate and we advise oral corticosteroids in its treatment.
