Case contributed by Ammar Haouimi
Diagnosis probable

Presentation

Left maxillary swelling.

Patient Data

Age: 40 years
Gender: Male

There is an expansile lytic lesion of the left maxilla with scalloped, well-corticated margins, expanding into the ipsilateral maxillary sinus with cortical breach. No periosteal reaction or involvement of the adjacent soft tissue is seen. 

Case Discussion

CT features suggestive of an odontogenic keratocyst. In the presence of bony destruction, ameloblastoma should be considered in the differential diagnosis.
