[Computerized axial tomography (CAT) and echography (US) of multilocular cystic nephroma].
OBJECTIVE
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.
