A 63-year-old man presented for evaluation of an incidental, unilocular lesion with benign cortical thinning of the left posterior mandibular body. The lesion, which was located immediately beneath the inferior alveolar nerve canal, had been identified on a panoramic radiographic (Panorex) study performed during a routine dental evaluation (Figure 1). The patient was otherwise asymptomatic and denied any complaints referable to the head and neck. He denied any history of trauma to the facial region. Physical examination revealed intact sensation along the distribution of the inferior alveolar and mental nerves bilaterally. Noncontrast magnetic resonance imaging demonstrated scalloping of the lingual surface of the posterior mandible, near the angle of the left mandible, as well as soft tissue extending into this area that was contiguous with the adjacent left submandibular gland (Figure 2 and Figure 3).
