Emphysematous pyelonephritis (EPN) is a rare and severe form of acute pyelonephritis. Escherichia coli accounts for 60% of the cases. Predisposing factors are: diabetus mellitus, recent urinary tract infection and obstruction. There is a female predominance (2/1). Conventional radiography reveals the renal emphysema in 85% of the cases. Ultrasonography shows hyperechoic areas corresponding to the gaz. CT scan is the best technique, allowing the exact localization of the gaz inside the renal parenchyma. The natural course of the disease allows its radiologic classification in 4 grades. EPN has a poor prognosis if only a medical treatement is initiated. Every urinary tract infection, in a diabetic patient must be treated, and must lead to a radiologic exploration, which allows an early detection of severe forms of the disease.
