Diagnosis of renal lymphoma in a dog

The report describes ultrasonographic findings of kidney lymphoma as an added tool in diagnosis of renal lymphoma in a female spitz. The animal was presented with history of inappetance, generalized lymphadenopathy, vomiting and diarrhea. Radiography, ultrasonography and fine needle aspiration cytology (FNAC) of lymph node and kidney cortex were performed. Ultrasonography findings of renal lymphoma showed protrusion on kidney’s cortical surface and hypoechoic circumscribed changes in cortico medullary region. Ultrasonography assisted aspiration for cytology and confirmed canine renal lymphoma diagnosis. Hematobiochemistry not showed much changes and X-ray revealed splenomegaly. After death of animal, changes on kidney cortical surface were noticed and biopsy also confirmed presence of renal lymphoma.
