Cavernous hemangioma of urinary bladder occurs relatively infrequently, accounting for 0.6% of all bladder tumors 1-3 with few cases reported in the literature (Table 1). Bladder hemangiomas result from embryological remains of unipotent angioblastic cells (of mesenchymal origin) that develop in an anomalous way inside the blood vessels. 4,5 Most urinary bladder CH are solitary and smaller than 3 cm in diameter, affecting the dome, posterior wall, or trigone of the bladder. 5,6 This tumor may occur sporadically or coexist with other benign and malignant vascular lesions such as cutaneous hemangiomas, Klippel-Trenaunay syndrome, Sturge-Weber syndrome, encephalo-trigeminal-angiomatosis, Osler-Weber-Rendu disease, hemorrhagic telangiectasia syndrome
