Enterococcus hirae bacteremia associated with perinephric collection and renal abscesses in a diabetic woman

Abstract

ABSTRACT Enterococcus hirae infection accounts for about 1% of all enterococcal infections. This number is likely to be underestimated because of inadequate identification. Human infection due to E. hirae is rarely reported. We present the case of a young woman with diabetes mellitus who developed symptoms of pyelonephritis and diabetic ketoacidosis. Renal computed tomography scan revealed the presence of subcapsular perinephric collection and renal abscesses. Her blood culture yielded E. hirae. Our patient was successfully treated with antimicrobials based on the susceptibility result. To our knowledge, this is the first reported case of perinephric collection and renal abscesses associated with E. hirae bacteremia.
