title: Osseous hemangiopericytomas of unsuspected intracranial origin.
abstract: Two cases of osseous hemangiopericytoma are presented that were initially diagnosed as primary in origin, but later reclassified as metastases, after a history of resection for an intracranial tumor was discovered. An intracranial source should be excluded before an isolated osseous tumor is determined to be a primary hemangiopericytoma.
