Emphysematous cystitis (EC) is a rare form of acute complicated urinary tract infection (UTI). We report a case of EC with bladder diverticulum. A 77-year-old man who had a medical history of diabetes mellitus was admitted to our hospital with the chief complaint of macrohematuria and pneumaturia. Based on the findings of an abdominal computed tomography and cystoscopy, the diagnosis of EC and bladder diverticulum was made with its characteristic feature being gas within the bladder wall and lumen and a cystic lesion from the bladder. His condition improved immediately with a combination of bladder drainage and appropriate antibiotics. The cystography revealed a very large diverticulum causing incomplete bladder emptying and stagnation of urine. We considered diabetes mellitus and a large amount of residual urine after urination due to bladder diverticulum and neurogenic bladder as the possible causal factors of EC in this case.
