Fig. 2. A. A panoramic radiograph shows a round radiolucency around the distal root of the left first mandibular molar. The root of the second molar is displaced distally. B. A coronal CBCT image shows a well-defined mixed radiopaque and radiolucent lesion in the left mandible. The lesion has slightly expanded to the lingual side. C. An axial CBCT image shows showing lingual expansion of the lesion. Radiopaque foci are observed within the lesion, and a thin, radiopaque rim is visible. D. A sagittal CBCT image shows a moderately defined lesion border.
