Benign osteoblastoma of the temporal bone: case report and literature review.

We report a case of benign osteoblastoma of the temporal bone and a review of the literature. Osteoblastoma is a rare bony tumor that usually develops in the long bones or in the vertebral column. To our knowledge, this is the fourth reported case of benign osteoblastoma confined to the temporal bone, and it is the second such reported case to include facial paralysis as the initial symptom. Result of computed tomography scan, magnetic resonance imaging scan, and angiography are reported. The diagnosis and management of this type of lesion are also discussed.
