Abstract
A six-years-old neutered male Labrador Retriever was presented with haematuria and
inappetence of one-week duration. Physical examination revealed mild abdominal pain
and the blood cell count showed moderate polycythaemia, with a slight increase of the
erythropoietin levels.Urinalysis demonstrated proteinuria, haematuria and isosthenuria
and urinary sediment revealed mild amount of lymphoid cells. After performing a complete
imaging study (radiographs, ultrasound and CT scan), a unilateral renal lymphoma
with secondary extranodal lymphoma of the urinary tract (bladder wall and left
ureter) was suspected. Fine-needle aspirates of both kidneys, ureter and bladder masses
were obtained, and a tentative diagnosis of lymphoma was made. Positive PCR antigen
receptor rearrangement indicated a T-cell origin. The owners opted for euthanasia and
declined necropsy. CT was essential for the evaluation of this case, not only depicted
renal lesions, but also identified accurately extension to adjacent anatomic structures
helping to determine the systemic spread of the disease.
