Case ReportsDelayed manifestation of spinal metastasis: a special feature of hemangiopericytoma.
Metastatic hemangiopericytoma to the spine is rare, and operative management of these highly vascularized tumors is challenging. Review of the literature identified only seven previously reported cases. Metastases of hemangiopericytomas to the spine are diagnosed often only after a long delay following resection of the primary tumors. ⋯ One year later, however, new metastases were present. Patients with hemangiopericytoma should be controlled regularly for local recurrence and systemic tumor spread. The best available treatment for delayed metastasis to the spinal column is complete tumor removal followed by postoperative radiotherapy.
