There is an expansile lytic lesion involving the left mandible, measured at approximately 34 x 16 x 32 mm. There is cortical destruction at the buccal surface. 37 and 38 are both absent. The lesion extends to the left mandibular canal. Artefacts from filling of 36 noted. Soft tissue component of the tumour is seen together with gas. The outer cortical margin of the left hemimandible is preserved. The upper aspect of the left mandibular ramus is intact. No other focal bony destructive lesion identified within the mandible. No significant abnormality is seen within the TM joints. Minimal mucosal thickening is seen in the right maxillary sinus base. Several lymph nodes are evident within the neck, without significant lymphadenopathy.
CONCLUSION:
There is a focal bony expansile destructive lesion in the left hemimandible in keeping with aameloblastoma or a KCOT.
