A perinephric abscess caused by Streptococcus agalactiae / 대한내과학회지

ABSTRACT

Group B streptococcus (GBS, Streptococcus agalactiae) has recently been recognized as an important, increasingly common cause of invasive disease in non-pregnant adults with underlying medical conditions. Diabetes mellitus, malignancies, liver cirrhosis, and previous trauma history increase the risk for invasive GBS disease. We report a rare case of perinephric abscess caused by GBS in a non-pregnant diabetic woman. A 24-year-old woman with diabetes and a history of urinary tract infection presented with a 4-week history of intermittent febrile sensation, chills, right flank pain, and anorexia. Computed tomography revealed an 8-cm right perinephric abscess. She was treated with percutaneous drainage of the abscess and intravenous antibiotics directed at the GBS, which had grown from the abscess drainage. She had a satisfactory clinical course.
