Chronic Pyelonephritis

Imaging findings are characterized by renal scarring, atrophy and cortical thinning, hypertrophy of residual normal tissue, caliceal clubbing secondary to retraction of the papilla from overlying scar, thickening and dilatation of the caliceal system, and overall renal asymmetry.

Emphysematous Pyelonephritis

• Additional evaluation with CT will confirm the presence and extent of parenchymal gas and will often allow identification of the source of obstruction when present.
• The use of intravenous contrast material will often reveal asymmetric renal enhancement or delayed excretion, and, during the nephrographic phase, will help identify areas of focal tissue necrosis or abscess formation.

Xanthogranulomatous Pyelonephritis

The CT findings of xanthogranulomatous pyelonephritis are pathognomonic in most cases: diffuse reniform enlargement with ill-defined central low attenuation, apparent cortical thinning, and central calculi.

• • Extension into the perinephric space and beyond the Gerota fascia is not uncommon.
  • Central areas of low attenuation represent nonenhancing xanthomatous material that may demonstrate attenuation values less than those of water.
