Pre- and post-contrast CT was performed. No evidence of pulmonary metastatic disease. Only the caudal thorax was imaged therefore the thoracic lymph nodes were not evaluated. Moderate volume free fluid throughout the dependent abdomen; large volume of fluid in the caudal-most abdomen. No distinct mass lesion within the peritoneum. The jejunal lymph nodes were normal size. Medial iliac lymph nodes appeared normal and were approximately the same diameter as the bifurcation branches of the aorta (approximately 5 mm wide). The adrenal glands were normal diameter (right measured 9.2 mm wide, left measured 7.0 mm wide). No evidence of nodules or masses in the liver. Spleen mildly enlarged, but no distinct mass lesion noted. The pancreas was mildly enlarged in the body region, but this may be a normal variant. Contrast noted within the pelvic regions of both kidneys and the ureters, and urinary bladder. No lesions noted. No distinct evidence of an invasive mass within the abdomen. At the caudal-most edge of the free fluid in the left dependent abdomen there was continuity between the free fluid and the abdominal musculature. This may represent an invasive mass or contiguousness of the free fluid and the intraperitoneal layer. No distinct evidence of the historically reported right-sided mass. The imaging ended prior to the right coxofemoral joint. Extensive degenerative changes in the right stifle. No evidence of aggressive lesions. Possible small volume free fluid adjacent to mildly atelectatic lung lobes in the pleural space.
