Case report: Hemangioma of the urinary bladder showing vascular inactivity and spontaneous regression

Background: Bladder hemangioma is a rare benign vascular tumor occurring in any age group. It may occur singly or in association with systemic arteriovenous malformations. Methods: We report a case of bladder hemangioma in a 35-year-old man who was admitted to our hospital for the evaluation of painless hematuria. Computerized tomography and MRI demonstrated bladder wall thickening with multiple foci of calcification in the vascular tumor. Results: Immediately after biopsy and lesion fulguration, the hematuria disappeared. The spec- imen was pathologically diagnosed as cavernous hemangioma of the urinary bladder. To establish the extent of tumor pelvic angiography was performed and showed no vascular activity in tumor. Conclusion: Lack of vascular activity on angiography and the calcifications of the tumor mass as seen on intravenous pyelography, computerised tomography and magnetic resonance sug- gested that it was partially or completely thrombosed and regressing, suggesting a conservative approach wherever possible. Spontaneous regression of such lesions has not been documented in the literature so far.
