Multiple Spinal Metastases of Hemangiopericytoma: Case Report

ABSTRACT

The authors report a case of multiple spinal metastasis from a meningeal hemangiopericytoma. A 35-year-old man who had undergone radical resection of temporal hemangiopericytoma presented with a two-month history of worsening low back pain and severe radiating pain on the left leg. Radiologic examination demonstrated a tumor involving body, pedicle and facet joint on the left side of L4 compressing dural sac with large paraspinal extension. Also there was a small tumor on left side pedicle and posterior body of T10. Satisfactory results were obtained after gross total resection of tumors on both regions with posterior lumbar instrumented fusion. Unlike a well differentiated tumor on temporal lesion, the metastatic spinal lesions were anaplastic histologically. Multiple spinal metastasis should be considered after surgical treatment of cranial hemangiopericytoma.
