An unusual case of large, destructive stafne bone cavity with computed tomography findings

Stafne bone cavity (SBC) is an asymptomatic lingual bone depression that usually described as a small oval homogenous radiolucency in the posterior mandibular region. The radiographic appearance and location of the SBC are characteristic and easily identified. The diagnosis can be confirmed by computed tomography (CT) scans, magnetic resonance (MR) imaging or sialography. This report describes a case of SBC in a 61-year-old male asymptomatic patient, presenting as a radiolucency in the left mandibular body with loss of buccal and lingual cortical plates on three-dimensional CT scan.
