Abstract:
We report a renal capillary hemangioma mimicking renal cell carcinoma to highlight a diagnostic pitfall. A 71-year-old woman with right flank pain had a 37-mm hypervascular right renal hilar mass with heterogeneous enhancement on multiphasic computed tomography (CT), suspicious for renal cell carcinoma (RCC). Robot-assisted radical nephrectomy was performed due to malignant concern and hilar anatomy. Histopathology showed capillary-sized vascular channels lined by bland endothelial cells, confirming capillary hemangioma with negative margins and no malignancy. This case underscores that benign vascular tumors can resemble RCC on imaging; awareness may aid differential diagnosis and reduce overtreatment in selected patients.
