title: Unusual extraosseous extension of jaw lesion into the temporal fossa.
abstract: The keratocystic odontogenic tumor (KCOT) is a relatively rare, benign neoplasm that develops in the maxilla or mandible, arising from the dental lamina or basal cells of the oral epithelium. The disease is characterized by aggressive growth and a high recurrence rate following surgical treatment. We present a case of a 55-year-old man with a giant KCOT of the mandible. The imaging features and differential diagnosis are described with discussion of the surgical management.
