Cholesterol Granuloma of the Frontal Bone

Abstract

Cholesterol granuloma of the frontal bone is a distinct clinical entity. This expanding lesion grows slowly within the diploe of the frontal bone until it extends into the orbit and causes globe displacement. We report the clinical and the CT findings in 11 patients with cholesterol granuloma of the orbit. The CT characteristics of cholesterol granuloma of the frontal bone appear to enable a correct preoperative diagnosis.
