SMALL ANIMAL
Species: Canine
Breed: Blue Heeler
Age: 12
Sex: Male

History: Owned by radiologist (ultrasonographer). Owner was able to document mass in liver with ultrasound, however, was unaware of presence of other lesions.

Findings: Multiple masses noted in liver. Gadolinium contrast intensifies the signal on tumors. Enlarged mesenteric lymph nodes noted as well. There are focal areas of increased signal within the liver parenchyma that enhance with gadolinium contrats material, consistent with metastatic infiltration. On dorsal views there is enlargement of the hepatic lymph nodes, suggesting further metastasis within the abdomen.

Impressions & Recommendations: Findings are consistent with hepatic neoplasia with regional lymph node involvement. Liver biopsies have been obtained and the patient is undergoing chemotherapy at the present time.

Species: Canine
Breed: German Shepard
Age: 6
Sex: Female

History: Acute rear leg paralysis with uninary incontenence.

Findings: This is a lateral T1-weighted MRI image of the lumbosacral region. There is loss of normal signal from the terminal portions of the spinal cord associated with extrusion of disc material with impingement of the terminal nerve roots within the spinal canal at the level of L7-S1.
