Abstract A six‐year‐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 – it not only depicted renal lesions, but also identified accurately extension to adjacent anatomic structures helping to determine the systemic spread of the disease.
