There is a unilocular lytic lesion in the angle of the right hemimandible extending anteriorly from the lateral root of the second molar to the ascending ramus of the mandible posteriorly. The inferior alveolar nerve canal courses along the posterior aspect of the lesion with focal area of dehiscence of the canal; it then courses inferior to the canal in the body of the mandible. The internal attenuation is noted of the fluid attenuation. There is no pathological fracture, periosteal reaction or extraosseous tissue extension.
Unremarkable appearance of the the remainder of the mandible with enlocated temporomandibular joints. The imaged paranasal sinuses are clear. The pituitary fossa is incompletely imaged and it contains partially imaged adipose tissue. No large mass lesion in the imaged intracranial compartment.
There is a unilocular lytic lesion in the right mandibular angle with imaging appearances of either keratocystic odontogenic tumour or a unilocular ameloblastoma .
