We report a 32-year-old woman with chronic kidney disease on hemodialysis undergoing a nephrectomy for left xanthogranulomatous pyelonephritis with a coralliform calculus and septic shock. Her clinical evolution was torpid, subfebrile, with persistent elevation of inflammatory parameters and with the finding of intra-abdominal collections interpreted as post-surgical. Finally faced with microbiological evidence of infection of the collections, the patient was operated and tended to improve. Read More

Department of Nephrology, Dayanand Medical College and Hospital, Ludhiana, Punjab, India.

Xanthogranulomatous pyelonephritis (XGPN) is an uncommon chronic destructive granulomatous inflammation of the kidney with variable clinical and radiological presentation. Due to its similarities to other benign and malignant pathologies, a high index of suspicion is required for preoperative diagnosis, which will ensure appropriate management of this condition. The invasion into the surrounding structures such as pararenal spaces, psoas muscle, small bowel, diaphragm, lung or soft tissues has been reported. Read More

Division of Interventional Radiology, Department of Radiology, University Hospital Waterford, Waterford City, X91 DWX0, Ireland.

Xanthogranulomatous Pyelonephritis (XGP) is a rare, chronic granulomatous inflammatory condition thought to arise secondary to a combination of obstruction, recurrent bacterial infection and an incomplete immune response resulting in focal or diffuse renal destruction. This destruction may be profound with the potential to infiltrate surrounding tissues and viscera. The imaging features of XGP can be ambiguous, mimicking malignancy, tuberculosis (TB) and malakoplakia earning the title of "the great imitator". Read More
