Orthopantomogram X-ray and noncontrast computed tomography of the face was done which depicted mixed radiolucent-radio-opaque lesion involving right posterior mandible, extending from distal of second premolar till third molar region, with radiolucency predominantly in the third molar region [Figure 2a]. In order to assess distant tumor metastasis, contrast enhanced computed tomography of thorax and abdomen was done which was suggestive of cavitary lesion in bilateral lungs, mediastinum, right adrenal gland and right femoral neck [Figure 2b-e].
