title: Large giant cell reparative granuloma of the petrous bone--case report.
abstract: 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. Histological examination revealed that the tumor consisted of massive fibrohistiocytic proliferation with numerous heavily hemosiderin-laden macrophages and numerous multinucleated giant cells. The most probable diagnosis was giant cell reparative granuloma. Therefore, no postoperative irradiation or other adjuvant therapy was given.
