The clinical, radiographic and histological features of synovial osteochondromatosis
in multiple joints and an unrelated sclerosing osteosarcoma of the left tibia in a
cat are reported. Radiographic evaluation showed signs of several nodular radiopacities
in both stifles and both shoulders. Pathologic transverse fractures of the left tibia
and fibula were also present. A midfemoral amputation of the left hindlimb was performed
and treatment consisted of lifelong administration of nonsteroidal anti-inflammatory
drugs. Histological evaluation confirmed synovial osteochondromatosis of the left
stifle and sclerosing osteosarcoma of the left tibia. This is the first report of
a feline patient with bilateral synovial osteochondromatosis that describes the clinical,
radiographic and histological aspects of this disease.
