Hemangiopericytomatous meningioma metastasized to the liver: Report of a case and review of the literature


A 54-year-old male was admitted to our hospital for treatment of a liver tumor which was pointed out by screening ultrasonography. Computed tomography revealed a tumor in the right lobe of the liver measuring 7 cm in diameter. Angiography revealed a hypervascular tumor. A hepatocellular carcinoma or hypervascular metastatic tumor was suspected. A right hepatic lobectomy was performed. The patient had previously undergone operations for a hemangiopericytomatous meningioma in the occipital fossa in 1972 and 1977. The histological findings of the liver tumor were identical to those for hemangiopericytomatous meningioma, so the etiology was considered to be liver metastasis from the previous meningioma. Nineteen cases of extracranial metastasis of hemangiopericytomatous meningioma have been reported in the literature, but hepatic resections of this metastasizing tumor have been very rare.
