title: Hemangiopericytic meningioma with extracranial spread to multiple sites without intracranial recurrence.

Metastases developed in his right femur 2 1/2 and 4 1/2 years post operation; he received radiotherapy both times.

The case is discussed with special attention paid to the path tumor spread.
