[Radiologic aspects of non-Hodgkin lymphomas of the kidney]

The authors review a series of 992 patients presenting with non-Hodgkins lymphoma and treated by the Milan Cancer Institute between 1968 and 1977. Intravenous urography was performed in 237 cases but only revealed 9 patients (3.8%) with non-Hodgkin lymphoma. Comparison of this low percentage with the 35% shown by necropsy examinations (9 mths) highlights the difficulty of detecting this condition by urography. The authors therefore recommend completion of the diagnosis by other radiological techniques (CT scan, renalarteriography (3 cases) and non-invasive examinations (ultrasound scanning, or Ga67 scintigraphy).
