Imaging Manifestations of Acute and Chronic Renal Infection That Mimics Malignancy: How to Make the Diagnosis Using Computed Tomography and Magnetic Resonance Imaging.

Can Assoc Radiol J 2019 Nov 17;70(4):424-433. Epub 2019 Sep 17.

Department of Medical Imaging, The Ottawa Hospital, University of Ottawa, Ottawa, Ontario, Canada. Electronic address:

Purpose: To review the computed tomography and magnetic resonance imaging manifestations of acute and chronic renal infections that may mimic malignancy and to provide useful tips to establish an imaging diagnosis.

Conclusion: Acute and chronic bacterial pyelonephritis are usually readily diagnosed clinically and on imaging when the diagnosis is suspected based upon clinical presentation. When unsuspected, focal, extensive or mass-like, acute and chronic bacterial pyelonephritis may mimic infiltrative tumours such as urothelial cell carcinoma (UCC), lymphoma, and metastatic disease.

Complicated Genitourinary Tract Infections and Mimics.

Curr Probl Diagn Radiol 2017 Jan - Feb;46(1):74-83. Epub 2016 Feb 11.

Mallinckrodt Institute of Radiology, St. Louis, MO.

This article provides pictorial review of complicated upper and lower genitourinary infections and their mimics. Imaging features of upper urinary tract infections including uncomplicated acute pyelonephritis, xanthogranulomatous pyelonephritis (XGPN), emphysematous pyelonephritis, perirenal abscess, and pyonephrosis are first reviewed and then followed by pictorial review of their mimics including contrast-associated nephrotoxicity, renal infarcts, malakoplakia, renal cell cancer, leukemia or lymphoma and Castleman's disease. Next, imaging features of lower urinary tract infections including cystitis, emphysematous cystitis, enterovesical, colovesical and vesicovaginal fistulas, Fournier gangrene, prostatitis, epididymitis, and orchitis are reviewed and then followed by pictorial review of their mimics including gas in the bladder and perineum related to instrumentation, radiation cystitis, bladder cancer, testicular torsion, testicular trauma, and testicular cancer and lymphoma.

A Rare Case of Pneumoureter: Emphysematous Pyelitis versus Emphysematous Pyelonephritis.

J Clin Diagn Res 2015 Nov 1;9(11):TD03-5. Epub 2015 Nov 1.

Senior Resident, Department of Radiodiagnosis, K V G Medical College & Hospital , Sullia, Dakshina Kannada, Karnataka, India .

Emphysematous pyelitis is a rare benign entity which is defined as isolated gas production in the pelvicalyceal system, ureters or in the urinary bladder as a consequence of acute bacterial renal infection. In this case report we present a case with no prior medical history of diabetes or urinary obstruction who presented with uncontrolled hyperglycaemia for the first time associated with emphysematous pyelonephritis. Further, the imaging differences between emphysematous pyelonephritis (EPN) and emphysematous pyelitis (EP) has been discussed along with the approach and their management. Read More

Binzhou Medical University, No. 346, Guanhai Road, Laishan District, Yantai 264003, Shandong, China. Electronic address:

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.

[Emphysematous pyelonephritis in a non-diabetic patient with a kidney tumour].

Ugeskr Laeger 2015 Mar;177(14):V10140576

Urologisk Afdeling, Roskilde Sygehus, Køgevej 7-13, 4000 Roskilde.

Emphysematous pyelonephritis (EPN) is a potentially life-threatening infection, where gas produced by bacteria accumulates in the kidney and the surrounding tissue. Although EPN usually presents in diabetic women, it is also associated with urinary tract obstruction and kidney tumours in non-diabetic patients. We present a case of EPN in a non-diabetic patient with a known kidney tumour, successfully treated with double-J catheter, antibiotics and delayed nephrectomy. Read More
