Rare massive hepatic hemangioblastoma: A case report

BACKGROUND Hepatic hemangioblastoma is an extremely rare disease; only three cases have been reported in the literature, and its magnetic resonance imaging (MRI) findings are unreported. CASE SUMMARY We report a case of incidental hepatic hemangioblastoma. The patient had no history of von Hippel-Lindau disease or associated clinical signs. Computed tomography and MRI showed a large tumor occupying almost half of the right side of the liver with expansive growth, well-defined borders, heterogeneous mildly progressive enhancement, and visibly enlarged blood supply vessels. Flow voids were observed on T2-weighted imaging. Both diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) map findings of the mass were predominantly inhomogeneous. Postoperative pathology indicated a diagnosis of hemangioblastoma. CONCLUSION Enlarged peripheral blood-supplying vessels and progressive enhancement seem to be typical imaging features of hepatic hemangioblastoma. However, a solid significantly enhanced mass with a low signal on DWI and a high signal on ADC may also be helpful for the diagnosis of hepatic hemangioblastoma.
