Large giant cell reparative granuloma of the petrous bone--case report.

A 41-year-old man presented with a large mass bulging over the suprazygomatic temporal region. Neuroradiological examination showed that the huge extra-axial mass with osteolytic character originated from the upper surface of the petrous bone. Preoperative obliteration of the feeding arteries with super-selective intravascular embolization was helpful for the total removal of the tumor.
