RT Journal Article SR Electronic T1 A rare and unusual presentation of urological infection on a patient on steroids JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2012007570 DO 10.1136/bcr-2012-007570 VO 2012 A1 Tsong Kwong A1 Charles Coker A1 Emma Simpson YR 2012 UL http://casereports.bmj.com/content/2012/bcr-2012-007570.abstract AB We report the rare case of adult lobar nephronia in a 49-year-old female, on long-term steroids with no prior urological or transplant history. More frequently reported in paediatric literature, adult lobar nephronia (focal pyelonephritis) is an unusual radiological finding sometimes preceding the development of renal abscess. We advocate that treatment should be a prolonged course of antibiotics and close follow-up.
