On intraoral examination [Figure 1], a diffuse swelling was present in the right buccal vestibule adjacent to the right mandibular canine, premolars and the first molar obliterating the buccal vestibule.

Mandibular occlusal radiograph [Figure 2a] revealed a well-defined radiolucent lesion with respect to the right mandibular canine, premolars and first molar with expansion and thinning of the buccal cortical plate. Orthopantomogram [Figure 2b] revealed a mixed radiopaque - radiolucent lesion with a hazy radiopacity surrounded by a well-defined radiolucent lesion on right side of mandible above the mental foramen. Cone beam computed tomogram [Figure 2c and d] revealed a well-defined expansile lytic lesion in the axial view, present on the right side below the level of roots which revealed a well-defined circular rim of hyperdense mass present within the outer hypodense mass.

Orthopantomograph [Figure 5a] revealed a large roughly oval mixed radiopaque - radiolucent lesion in the right posterior maxillary region distal to the maxillary right second molar which seemed to be pushing the floor of the right maxillary sinus superiorly. Paranasal sinus view [Figure 5b] revealed a similar large mixed lesion in the posterior right maxilla. Coronal and axial sections of computed tomography scan [Figure 5c and 5d] revealed a well-defined hyperdense mass in right maxillary tuberosity region along the posterolateral walls of the right maxillary sinus.
