Abstract

Emphysematous cystitis is an uncommon infection of the urinary bladder with the formation of carbon dioxide either inside the bladder cavity or within its wall. A 91-year-old non-diabetic woman was admitted for an intertrochanteric fracture of the femur. The patient also complained of lower abdominal pain. An abdominal flat X-ray revealed intramural and intraluminal air in the distended bladder indicating emphysematous cystitis, however, these findings passed unnoticed. We present the serial radiologic changes of an undetected emphysematous cystitis. The diagnostic and therapeutic aspects are discussed.
