Computed Tomography (CT) of the Stifle 151Figure 20.15 Radiograph and
corresponding CT image of the distal
part of the femur showing new bone
formation and subchondral sclerosis in
the area of the medial fabella (white
arrows). These lesions are hardly
visible on the radiograph.
(A)(B)Figure 20.16 (A) Radiographs of a
6-year-old Bernese Mountain Dog with
a synovial cell sarcoma. The
radiographs show several
radiolucencies in the subchondral
bone (arrows). (B) Transverse images of
the distal femur and proximal tibia
clearly demonstrating the osteolysis
caused by the tumor (arrows). One
transverse image in a soft-tissue
window after intravenous contrast
administration shows enhancement of
the severely swollen synovia (black
arrowheads). These CT images better
show the extent and severity of the
neoplastic process. (C) Sagittal and
dorsal reconstructed images giving a
clear overview of the extent of the
tumor.
