Fig. 4-57 A 10-year-old female Doberman Pinscher with a
right limb lameness and generalized stiffness with difficulty
getting up and down. Multiple cutaneous nodules were
present. Both right and left rear limbs were radiographed.
The right stifle is illustrated. There are multiple areas of
increased medullary density involving the distal right femur
and proximal and middle portions of the right tibia. Similar
densities were noted within the diaphysis and metaphysis of
the left femur and tibia. These intramedullary densities with
no evidence of periosteal proliferation are suggestive of disseminated
bony metastasis. Diagnosis: Metastatic carcinoma.
Fig. 4-58 A 6-year-old male English Pointer had been lame in the
right hind limb for 1 week. There is a focal lytic lesion in the lateral epicondyle
of the femur (arrows). Diagnosis: Metastatic bronchogenic
carcinoma.
