Magnetic resonance imaging and computed tomography findings of vertebral osteosarcoma in a cat. [Journal Article]
J Vet Med Sci 2009 Apr; 71(4):513-7.
An 8-year-old female Persian cat with a gait disorder was brought to our hospital. Pelvic limb mobility had gradually reduced over the preceding 3 months, then rapidly deteriorated 2 weeks before consultation. Signs also occurred in the thoracic limbs. With a tentative diagnosis of neural disease, magnetic resonance imaging and computed tomography were performed. T1-weighted imaging showed isointensity in the seventh cervical vertebra, while T2-weighted imaging revealed hypointensity. Contrast-enhanced T1-weighted imaging revealed a uniformly enhancing mass. Extirpation of the mass relieved the clinical signs, leading to disappearance of the neurological signs. The histopathological examination suggested osteosarcoma.
