Bilateral renal cortical abscesses in a young woman with type 1 diabetes

Serious complications of urinary tract infection, such as papillary necrosis or perinephric abscess, occur more frequently in diabetic patients. However, severe bilateral renal parenchymal infection with multiple intrarenal abscesses is not well recognized. We described an 18-year-old insulin-dependent diabetic woman with such infection, in whom renal imaging showed progression to a major perinephric abscess, but only after 5 weeks of intensive antibiotic therapy. Complete recovery followed surgical drainage and no renal cortical scarring was present on computerized tomographic scan 18 months later.
