Methods CT features of odontogenic cysts（n-17）, which are proved by surgery and pathology, are retrospectively analyzed, and the configuration and structure of the lesions are observed. Results Odontogenic cysts include dentigerous cyst（n=8）, periapical cyst（n=6） and keratotic cyst（n=3）, mainly display unilocular or lobulated, distinct margin with sclerosis. The ＂bony cyst in sinus＂ feature is characteristic. Conclusion Most lesions of odontogenic cysts havc a characteristic manifestation in CT.
