The patient was otherwise healthy with a noncontributory medical history. The clinical
examination did not reveal any dental source of infection. There was no swelling or
tenderness on palpation. A cone-beam computed tomographic (CBCT) scan showed a well-defined,
expansile radiolucency with radiopaque foci in the right posterior mandibular body
and angle region (
Figures 1,
2, and
3). The approximate size of the radiolucency was 27 millimeters (height) × 15 mm (width) ×
42 mm (length). An incisional biopsy specimen was obtained and submitted for histologic
examination (
Figure 4).
Figure 1
Reformatted panoramic cone-beam computed tomographic image shows a well-defined radiolucent
lesion with internal calcifications in the right posterior mandibular body and angle
region. The epicenter of the lesion is inferior to the mandibular canal (red). Note
the superior displacement of the canal.
Figure 2
Axial cone-beam computed tomographic image shows expansion and thinning of the adjacent
cortical plates. There is perforation of the lingual cortex without evidence of periosteal
reaction.
Figure 3
Coronal cone-beam computed tomographic image shows scattered flocculent or snowflakelike
calcifications in the internal structure of the lesion.
Figure 4
Photomicrograph shows irregular trabeculae of woven bone within a background of cellular
fibrous connective tissue (hematoxylin-eosin stain, original magnification ×100).
