Objectives:
To determine the sensitivity and specificity of computed tomography and ultrasound in the diagnosis of multilocular cystic nephroma.
Methods:
Four cases with a pathologically confirmed diagnosis of cystic nephroma were reviewed.
Results:
These four cases had a predominantly cystic mass with thin walls located in the lower pole of the kidney. Both techniques had a sensitivity of 100% for renal masses but a low specificity since they failed to distinguish multilocular cystic nephroma from other cystic lesions.
Conclusions:
A presumptive diagnosis of multilocular cystic nephroma can be made on the findings of these noninvasive diagnostic imaging techniques. The definitive diagnosis, however, is by anatomopathology.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
