Emphysematous Cystitis

 

Emphysematous cystitis is a rare form of bacterial cystitis that occurs in patients with poorly controlled diabetes. E. coli is the most common pathogen and urinary stasis is a common feature.

Radiographic findings include gas within the bladder (in the absence of bladder instrumentation) or within the wall of the bladder in a linear, streaky, or multi-cystic pattern.

Contrast enhanced CT of pelvis shows low density gas (arrows) in the bladder wall representative of emphysematous cystitis in the absence of any recent instrumentation.
