title: Severe emphysematous pyelonephritis mimicking intestinal obstruction.
abstract: Emphysematous pyelonephritis is a severe necrotizing infection characterized by the presence of gas and/or fluid in the renal parenchyma, collecting system, or perirenal tissues. Emphysematous pyelonephritis with approximately 15 cm air-fluid level, diffused ureteral involvement, and the accumulation of gas in liver and peritoneal cavity is very rare. Here, we reported a severe emphysematous pyelonephritis with multiple huge air-fluid level mimicking intestinal obstruction and with the accumulation of gas in liver and ureter in computed tomography imaging. The patient was successfully managed by percutaneous nephrostomy combined with medical treatment.
