Figure 1.9.21 Maxillary Fibrosarcoma (Canine) CT
11y Standard Poodle with enlarging left
maxillary mass. Representative CT images are
at the level of the maxillary canine teeth.
There is a left‐sided soft‐tissue mass with an
intranasal component, the latter of which has
resulted in adjacent ectoturbinate destruc­
tion (a: asterisk). The left maxillary canine
tooth is missing, and osteolysis of the alveo­
lus and lateral maxillary cortex is evident
(a: arrows). The mass moderately and hetero­
geneously contrast enhances (b). Biopsy
revealed fibrosarcoma.

12y MC Miniature Schnauzer with left‐sided facial swelling and an infraorbital draining tract. There is a mixed productive and destructive
mass originating from the left maxilla (a: arrows). The mass extends into the nasal cavity, obliterating the ventral nasal turbinates.
The mass is mildly enhancing on contrast‐enhanced images. Biopsy confirmed osteosarcoma.
