From the case:
Emphysematous cystitis
Axial non-contrast

Pelvic NECT confirms the diagnosis (only part of the pelvis shown because of metallic artifacts rending the rest of the exam useless). No extra-luminal air. There is a thickening of the bladder secondary to the inflammatory process.
Case Discussion
Emphysematous cystitis refers to gas forming infection of the bladder wall.
