Osteoblastoma involving the sphenoid bone diagnosed with percutaneous biopsy.

Abstract

Osteoblastomas are rare, benign, bone-forming tumors, most commonly appearing in the axial skeleton. Osteoblastomas arising in the skull are even rarer and tend to originate in the temporal and frontal bones, with involvement of the sphenoid bone being one of the least common sites described. This report discusses a case of an aggressive appearing osteoblastoma of the sphenoid bone that was diagnosed via percutaneous biopsy. A short review of pediatric skull lesions is also presented.
