A rare cause of hematuria in children: arteriovenous hemangioma of the bladder

Bladder hemangiomas are exceedingly rare benign tumors of the urinary bladder that account for 0.6% of bladder tumors [1]. Although this tumor can occur at any age, hemangioma in childhood is relatively rare [2]. Hemangiomas are classified as cavernous, capillary, or arteriovenous. Most hemangiomas of the bladder are of the cavernous type. In the literature arteriovenous hemangiomas have been described only in adults [3]. We report a case of arteriovenous hemangioma of the urinary bladder in a 14-year-old young boy. To our knowledge, this is the first reported case of an arteriovenous hemangioma in a child causing macroscopic hematuria.
