Hiromi KUDA1), Tomotada TAKAYAMA1), Naoya TONEGAWA1)

We report a case of an 11-year-old girl with 4 days of fever, left flank pain and costovertebral angle (CVA) tenderness. An echo-free space (60 mm×44 mm) in the left kidney was revealed by abdominal ultrasonography, and abdominal contrast enhanced computed tomography showed a renal abscess. Antimicrobial therapy began after computed tomography-guided percutaneous catheter drainage of the abscess. Streptococcus intermedius was isolated from culture of the abscess aspirate. S. intermedius presents in the oral flora of humans and, unlike other oral streptococci, is characterized by forming abscesses in the brain and liver. There have been no previous reports of renal abscess due to S. intermedius.
