Interpretation

Radiographic findings:

The kidneys are small (less than 2 times the length of L2) and irregular in contour A portion of the small intestine in the right mid to caudal abdomen appears focally enlarged in diameter and contains a mottled soft tissue and gas opacity. There is spondylosis at the caudal thoracic vertabrae. The left hindlimb is amputated at the level of the proximal diaphysis of the femur.
Findings concerning the kidneys are consistent with chronic disease and prior diagnosis of chronic renal failure. There may be a mural small intestinal mass

Ultrasonographic Findings:

The kidneys are irregular in contour. The left renal pelvis is dilated at 3.5mm and the right renal pelvis is dilated at 5mm. Multiple loops of small intestine have thickened walls with loss of normal wall layering. The most severe area is in the right abdomen and is 7mm thick. The colon wall is thickened at 2mm. There are multiple enlarged, hypoechoic lymph nodes in the mid abdomen.
Findings concerning the kidneys are consistent with chronic disease and prior diagnosis of chronic renal failure. Bilateral renal pelvic dilation is consistent with pyelonephritis or partial obstruction. Rule outs for the intestinal wall thickening and enlarged lymph nodes include neoplasia with lesser consideration given to granulomatous disease. Fine needle aspirates were obtained

FNA results:

Inconclusive

Necropsy results:

The abdominal cavity contained 200ml of yellow purulent fluid. There was fibrin adhered at several locations of the small intestine. The proximal jejunum contained a 4cm focal area where the mucosa/submucosa was thickened by a tan, homogenous mass. The mucosa at the periphery of the mass was necrotic. The distal colon had a corrugated appearance. The cortical surface of the kidneys was irregular and roughened. The liver was pale and had rounded margins. The left parathyroid gland was enlarged.

Histopathology results:

Small intestine: Lymphosarcoma.

Suppurative peritonitis

Kidneys: Chronic renal disease
