Abstract
We report a rare case of hepatic metastasis of meningeal hemangiopericytoma (HPC) 10 years after primary resection, mimicking hepatocellular carcinoma (HCC). The patient was a 55-year-old man and a follow-up computed tomography (CT) scan after resection of the meningeal HPC revealed two hypervascular hepatic tumors in segments 4 and 6. The hemodynamics of the tumors showed patterns of HCC. Posterior sectionectomy and partial resection of segment 4 was carried out as treatment. Microscopic findings of the resected specimen were massive growth of spindle-like cells surrounding the small vessels, which resembled the findings of the meningeal HPC resected 10 years ago. Therefore, our final diagnosis of these liver tumors was late metastases from HPC of the meningeal membrane, not HCC. The patient is doing well without recurrence 4 years after surgery. Recurrence of meningeal HPC to the liver successfully treated by surgical resection is a rare entity. As the liver metastasis of HPC shows a hypervascular appearance, differential diagnosis from HCC will be important.
