A 69-year-old woman presented to her dental surgeon with a painless swelling of the
left face, and no other signs or symptoms. Initial radiologic findings revealed a
multiloculated radiolucent area within the left mandible (Figure 1). Further clinical investigations included a computed tomography (CT) scan of the
cranium, sinuses, facial bones and cervical spine (Figure 2). A partially corticated oblong radiolucency was noted in the left posterior mandible
measuring approximately 40 × 20 × 12 mm. The lesion extended anteriorly from the left
mental foramen distally to the midramus area and superiorly from the crest to the
inferior border of the mandible. Mild buccal and lingual expansion was also observed.
The left inferior alveolar nerve canal was displaced buccally. There was no effect
on the roots of the surrounding teeth. The imaging report described multiple discreet
small opacities within the lesion, though these did not appear significant. No other
abnormalities were noted.
