Abstract:
Objective To discuss the X-ray and CT manifestations of keratocystic odontogenic tumour(KCOT)in mandible,to im-prove the diagnostic accuracy of the disease.Methods The X-ray and CT features of KCOT(n=25)in mandible,which were proved by surgery and pathology,were retrospectively analyzed.Results The KCOT,including solitary tumor(n=23)and multiple tumor (n=2),mainly displayed unilocular or multilocular in shape with distinct sclerosing margin.Disruption of the adjacent cortex was de-tected in 7 cases,growth along the long axis of mandible in 18 cases,compression and displacement of the adjacent teeth in 21 cases, resorption of bevel of roots in 2 cases.Conclusion Most lesions of KCOT in mandible have characteristic manifestation in X-ray and CT findings,which is helpful for diagnosis and differential diagnosis.
