Abstract:
We report a case of multiple hemangiomas involving the urinary bladder in a 4-year-old boy who presented with recurrent episodes of gross hematuria. On ultrasonography, compared with the bladder wall, the lesions presented as multiple isoechoic polypoid intraluminal masses with mildly increased vascularity on color Doppler exam. Cavernous hemangioma was confirmed by cold-cup biopsy, and the all lesions were coagulated with a Holmium laser. Despite their rarity, bladder hemangiomas should be included in the differential diagnosis of multiple intravesical masses in children with gross hematuria.
