The authors describe a rare case of hemangiopericytoma with cervical metastasis. A 34 year-old man with a history of intracranial hemangiopericytoma complained of a weakness of his right hand. Both CT scan and MR imaging demonstrated homogeneous enhanced tumor in his C5 vertebral body, right facet joint and lamina. Preoperative embolization was performed in order to decrease bleeding during the operation. A two-stage operation was performed because the tumor was considered to be too large to remove all at once. First, from the anterior, partial tumor resection and C5 corpectomy were done followed by anterior fusion with a cervical plate. After which, a secondary surgery was carried out from the posterior. The gross total tumor removal was accomplished successfully by these procedures. Histological findings revealed typical hemangiopericytoma. Despite fifty-four Gy of local irradiation subsequently being performed for cervical lesion to prevent tumor recurrence, multiple metastases have been revealed twenty-five months after the surgery. Careful and long follow up for hemangiopericytoma is essential even after gross total surgical removal and postoperative radiotherapy.
