Renal hemangioblastoma mimicking clear cell renal cell carcinoma: a case report emphasizing contrast-enhanced ultrasound findings

Sporadic RH should be included in the differential diagnosis of a small hypervascular renal mass that mimics ccRCC. In this case, relative hyperenhancement persisting at 180 s on CEUS may represent a nonspecific descriptive clue, but definitive diagnosis still requires integrated pathologic interpretation.
