Xanthogranulomatous pyelonephritis (XGP) in a pelvic ectopic kidney was diagnosed pre-operatively. CT scan findings, including central lithiasis and the
Area of Science:
- Nephrology
- Radiology
- Urology
Background:
- Ectopic kidneys present unique diagnostic challenges.
- Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic, destructive inflammatory process of the kidney.
Observation:
- A 70-year-old male patient presented with a pelvic ectopic kidney.
- The patient's condition involved Xanthogranulomatous pyelonephritis.
Findings:
- CT scan revealed characteristic features of XGP.
- Key findings included central lithiasis and multiple rounded low-density areas with enhancing rims, described as the 'bear paw sign'.
- This imaging pattern facilitated pre-operative diagnosis.
Implications:
- The 'bear paw sign' on CT is a valuable diagnostic indicator for XGP in ectopic kidneys.
- Accurate pre-operative diagnosis improves patient management and surgical planning.
- Highlights the importance of recognizing rare presentations of common conditions in unusual anatomical locations.
