Figure 1.3.13 Temporomandibular Fibrosarcoma (Canine) CT
6y M Golden Retriever with recent onset of
oral pain. A large, aggressive bone‐destructive
mass is centered on the caudal aspect of the
left side of the mandible. Osteolysis of the left
mandibular ramus (a: arrows) and condyloid
process (b: arrow) is evident. Bone destruction
extends to and includes the subchondral bone
of the process, implying an intraarticular com-
ponent to the mass. On comparable contrast‐
enhanced images, the mass has a complex,
lobular appearance (c,d). Aspiration biopsy
revealed the mass to be a fibrosarcoma.
