Today’s case is a 14-year-old Terrier with diabetes, who is now vomiting. Take a look and post your interpretation in the comments section.
The pylorus appears mildly enlarged on the lateral projection and is filled with fluid and granular material. The small intestine is uniform in diameter.
There are several irregular gas lucencies in the urinary bladder, best seen on the lateral projection. No calculi are visible. The kidneys are normal in size and shape.
- Emphysematous cystitis
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.
