title: Sphenoid bone: a rare site for giant cell tumor - case report with literature review.
abstract: While giant cell tumor is commonly a tumor of long bones, involvement of sphenoid bone is very rare. Clinically and radiologically, it mimics other neoplasms of this site. Endochondral ossification of this bone during development explains its curious preferential involvement in comparison to the rest of the skull bones. We describe an example of such a tumor arising in the sphenoid bone in a young woman and discuss the differential diagnosis. Recognizing its characteristic features is important for correct interpretation. .
