title: Liver metastasis of meningeal hemangiopericytoma: a study of 5 cases.
abstract: Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the primary meningeal tumor. In this report, the clinicopathological features of 5 cases of metastatic HPC to the liver were reviewed and described.
