The diagnosis of renal pseudotumours.
The radiological features of 13 cases of renal pseudotumour due to infolding of the columns of Bertin are presented. 5 of these patients (38%) had partial duplication of the renal pelvis. Pseudotumours show as space-occupying lesions at urography. At angiography they show a clearly defined nephrogram but no abnormal vessels, no pooling of contrast medium and no early venous filling. Radio-isotope scans on 4 cases of pseudotumour showed uptake at the site of the pseudotumour in contrast to cysts and carcinomas which are known to show diminished uptake.
