Urinary bladder hemangiomas are a rare cause of gross hematuria in young patients. Multimodality imaging with ultrasound, computed tomography, and magnetic resonance imaging help define the site and extent of hemangioma. We describe a case of an otherwise healthy 9-year-old male presenting with recurrent gross hematuria. The initial US did not demonstrate a bladder mass, but subsequent cystoscopies showed progressive enlargement of an extensive sessile and partially pedunculated vascular mass. Imaging with ultrasound, computed tomography, and magnetic resonance imaging persistently demonstrated a hypervascular bladder mass without extravesical extension. Ultimately, biopsy of the mass made the diagnosis of bladder hemangioma.
膀胱血管瘤是年轻患者肉眼血尿的罕见病因。超声、计算机断层扫描和磁共振成像等多模态成像有助于明确血管瘤的部位和范围。我们描述了一例9岁健康男性反复出现肉眼血尿的病例。最初的超声检查未发现膀胱肿块，但随后的膀胱镜检查显示一个广泛的无蒂且部分有蒂的血管性肿块逐渐增大。超声、计算机断层扫描和磁共振成像检查一直显示为膀胱内的高血管性肿块，无膀胱外扩展。最终，肿块活检确诊为膀胱血管瘤。
