title: Metastatic meningeal hemangiopericytoma of thoracic spine.
abstract: We report a case of metastatic meningeal hemangiopericytoma in thoracic spine. A 49-year-old female having a history of tentorial hemangiopericytoma first found 116 months before was admitted to our hospital with acute onset of paraplegia. Magnetic resonance image revealed a tumor invading the left lamina and pedicle of the 8th thoracic vertebra, and compressing the dural sac severely. After subtotal removal of the tumor, the patient showed rapid neurological improvement. The histological findings were characteristic of hemangiopericytoma. Because extradural metastases of meningeal hemangiopericytoma occur long after previous treatment in unexpected sites especially in skeletal system, repeated bone scintigraphy is essential.
