Presentation
Diabetes mellitus, well controlled. Recent onset of vomiting.
Patient Data
The pylorus appears mildly enlarged on the lateral projection, and is filled with fluid and granular material. There are several irregular gas lucencies in the urinary bladder, best seen on the lateral projection.
Impression:
Emphysematous cystitis.
Case Discussion
Emphysematous cystitis is commonly associated with diabetics since the glucose in the urine forms a hospitable environment for gas-producing bacteria. On ultrasound, there were multiple polyps associated with the dependent mucosa. Gas was visible in the bladder wall and free in the lumen. The urine culture resulted in growth of two types of hemolytic E. coli.
