RT Journal Article SR Electronic T1 Unusual CT Appearance in an Odontogenic Keratocyst of the Mandible: Case Report JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1887 OP 1889 VO 22 IS 10 A1 Yonetsu, Koichi A1 Bianchi, Jorge G. A1 Troulis, Maria J. A1 Curtin, Hugh D. YR 2001 UL http://www.ajnr.org/content/22/10/1887.abstract AB Summary: An expansile lesion in the body of the left mandible had high attenuation (225 HU) on nonenhanced CT scans. Histologic examination revealed an odontogenic keratocyst with no evidence of mineralization or calcification within the lesion. The high attenuation was considered to be due to highly concentrated protein of thick, viscous keratin in the lumen of the keratocyst.
