Osteoblastoma and Osteoid Osteoma of the Mandible: Review of the Literature and Report of Two Cases

Figure 1

Case #1 3D CT reconstruction (a) and bone window CT sagittal view (b) showing the mixed density lesion associated with impacted #17 measuring  cm. The border of the lesion is well circumscribed with a broad sclerotic rim surrounding a lucent halo. Axial views ((c-f) from superior to inferior) and coronal views ((g-j) from posterior to anterior) showing buccal and lingual expansion, thinning, and areas of perforation at buccal and lingual cortices (arrowheads). Extensive sclerotic reactive bone is seen surrounding the lesion. New bone formation can be seen at buccal, lingual cortical, and inferior to the lesion (arrows). The lucent rim of the lesion extends into the left mandibular canal, with potential involvement of the inferior alveolar nerve (g–j).
