Two factors may have concurred to its development: cystic artery compromise (in the setting of diabetes and renal failure) and immunosuppression. Gas-forming organisms (as primary or secondary infection)3 are frequent, with C. perfringens identified in 50% of cases.4 The outcome of this high mortality condition depends on immediate diagnosis and therapy.
