An Uncommon Complication of Emphysematous Cystitis and Pyelitis.

Psoas muscle abscesses associated with emphysematous urinary tract infections are rare. There are not many case reports about urinary tract infections such as emphysematous pyelitis and emphysematous cystitis complicating psoas muscle abscesses. Here, we report a case of an ipsilateral psoas muscle abscess following emphysematous cystitis and emphysematous pyelitis in an 81-year-old diabetic man. He was treated with prolonged antibiotic therapy and other supportive care.
