Patient presented on referral from her general dentist after noticing mild expansion of the right buccal vestibule during a routine dental examination. The area was firm and non-tender to palpation. A cone beam CT study was obtained, which revealed a well corticated, well circumscribed radiolucent lesion in the area and in a very close proximity to the inferior alveolar canal.
Figure 1 This panoramic radiograph was taken at first clinical presentation. Note the well-demarcated unilocular radiolucency with scalloped border involving area of teeth #s 28-30. Also note the thinning of the inferior border of the mandible with inferior expansion.
