A Case of Concomitant Emphysematous Cystitis and Clostridium difficile Colitis with Pneumoperitoneum.

Emphysematous cystitis (EC) is a rare condition described as air within the wall and lumen of the urinary bladder. It is a complicated form of urinary tract infection caused by gas-forming bacteria. Pneumoperitoneum described as gas in the peritoneum is usually seen with abdominal hollow organ perforation, and approximately 10% of cases have been reported that are not associated with abdominal hollow viscus perforation. To the best of our knowledge, no case of EC with pneumoperitoneum in the setting of concurrent urinary tract infection and () colitis have been reported. Here we present a unique case of EC with pneumoperitoneum, in a patient with recurrent infection and pneumonia-urinary tract infection, treated conservatively with a favorable outcome.
