We report a case of bladder hemangioma in a child. An 8-year-old girl was referred to our hospital for the evaluation of painless hematuria. Neither pyuria nor bacteriuria was detected. She had no dysuria. Intravenous pyelography showed deformity of the bladder without dilation of the upper urinary tract. Voiding cystourethrography revealed a filling defect of the bladder. Reddish blue masses were seen cystoscopically at the right wall and the dome of the bladder. Partial cystectomy was performed. From the histological findings, the diagnosis was cavernous hemangioma of the urinary bladder. Her postoperative course was uneventful and no recurrence was seen at the cystoscopical examination 3 months postoperatively. This is the 15th case of bladder hemangioma in children reported in Japan.
