Abstract
Emphysematous cystitis is a rare disease characterized by the presence of gas in the bladder wall and/or cavity. It predominates in diabetic women and its clinical symptoms are varied. We report a case of emphysematous cystitis in an unbalanced diabetic patient, discovered at the stage of septic shock and multivisceral failure following a cardiac decompensation with a rapidly unfavorable evolution. We suggest a probable role of low cardiac output in the genesis of this pathology in some patients.
