Intracranial hemangiopericytoma is an uncommon soft tissue sarcoma. We report a case of a 54-year-old Japanese female with hepatic metastasis from primary intracranial hemangiopericytoma. At age 44 years the patient underwent primary resection of the intracranial tumor, followed by no adjuvant therapy. At age 53 years she underwent resection of bone metastases in her left upper arm and tenth right rib. The following year, three hepatic tumors with high vascularity were detected by ultrasonography, computed tomography scans, and magnetic resonance imaging. An ultrasound-guided liver biopsy specimen confirmed the diagnosis of hepatic metastases from the primary intracranial hemangiopericytoma. A combination therapy of transcatheter arterial chemoembolization and radiofrequency ablation was performed against the hepatic metastasis. After 5 years, there has been no local recurrence in the liver.
