Hematuria in a newborn infant caused by bladder hemangioma

A newborn boy had gross hematuria caused by hemangiomas of the bladder. The sonographic examination and the voiding cystourethrogram showed an irregular and thick bladder wall with a lesion extending into the vesical lumen. Cystoscopic examination and biopsy of the lesions were diagnostic of hemangioma. Immediately after lesion fulguration, the hematuria disappeared, and 3 weeks later the follow-up ultrasound examination showed resolution of the lesion. At 1 year, the patient's urinalysis and ultrasound scan were normal. To our knowledge, this is the first reported case of hematuria in a newborn caused by a bleeding hemangioma of the bladder.
