Top image: Axial CT image of mandible in bone window setting reveals an
expansile lesion in the body of mandible on Rt side. The bony cortex of the
mandible is markedly thinned out by the lesion. No definite extension to the
Rt masseter muscle or tongue is demonstrated.
Bottom images: Axial CT images of mandible in soft tissue setting show the
lesion as homogeneous area of slight hypodensity compared to muscle.
Adjacent structures appears not involved by the lesion.
Legend
Top image: Coronal CT image of mandible in bone window setting
demonstrates again the expansile lytic bony lesion in the body of mandible
on Rt side. The lobulated medial border is well shown. The bony cortex
around the lesion, though significantly thinned out, appears intact.
Bottom images: Coronal CT image in soft tissue window setting show again
the lesion as slightly hypodense area. No definite calcification is note in the
lesion. The peripheral small hyperdense area seen medially in the Rt
image is likely due to partial volume rather than true calcification.
