A case of emphysematous cystitis in cystic fibrosis.

It is postulated that gas-forming organisms ferment glucose within the wall of the urinary bladder leading to air collection; emphysematous cystitis occurs due to the fermentation of glucose by these organisms. Emphysematous cystitis is a rare condition usually seen in patients who are either diabetic or have other immunosuppressive diseases, or have had disruption of the bladder wall due to trauma or surgical instrumentation. We present a case of emphysematous cystitis in a patient with cystic fibrosis without any other underlying immunosuppressive conditions which, to our knowledge, is the first reported case. The patient presented with abdominal pain and was diagnosed with abdominal computed tomography examination. She was managed conservatively with a favorable outcome.
