A Case of Renal Abscess with Septic Bilateral Buttock Abscesses

Abstract

We present a case of renal abscess with septic bilateral mobile buttock abscesses associated with diabetes mellitus. A 56-year-old man was admitted to our hospital for mild fever and pleural effusion. Staphylococcus aureus was detected by blood cultures. Two days after the admission, left buttock swelling appeared and was treated by antibiotics. Because it did not improve with antibiotics, surgical draining was performed. Three days after left buttock draining, his right buttock began to swell and the course was the same as the left side; antibiotics were not effective and surgical draining was performed. However although the bilateral buttock lesions were cured by surgical draining, intermittent fever continued. Ring enhanced cystic lesions of the right kidney was recognized by follow-up computed tomography and diagnosed as renal abscess. After percutaneous draining of the right renal lesion, intermittent fever improved immediately. The cause of the intermittent fever must be the renal abscess. Renal abscesses must therefore be taken into account when intermittent fever cannot be controlled by strong antibiotics therapy and local surgical draining.
