Stafne Bone Cyst: A Report of an Unusual Case

Stafne bone cyst (SBC) is a rare, asymptomatic finding typically located in the posterior region of the mandible, often observed incidentally on radiographs. The diagnosis of the defect is usually made using orthopantomogram, but in uncommon cases, more precise imaging techniques such as cone-beam computed tomography (CBCT), computed tomography (CT), and magnetic resonance imaging (MRI) are required. It is a well-circumscribed radiolucency that represents a developmental bone defect rather than a true cyst. This case report discusses a rare presentation of Stafne's bone cyst in a 30-year-old male patient, who also had concurrent pericoronitis. The radiograph incidentally showed a radiolucency below the mandibular canal in the left angle region of the mandible.
