Canine (Bernese Mountain Dog) · Radiograph — Abdomen
Presenting complaint
The patient presented for vomiting and abdominal discomfort. Owners suspect ingestion of cloth material approximately two days prior to presentation. He has passed stool containing torn towel material and has shown lethargy and pacing.
Imaging findings
A well-defined, round, amorphous aggregate of soft tissue opacity material with a peripheral rim of gas is present within the pyloric antrum. Striated heterogeneous soft tissue opacity content is noted within a loop of intestine, potentially duodenum, extending from T13 to L3. A fluid-filled loop of small intestine with suspended gas is identified in the right cranial abdomen. The majority of the small intestines are uniformly gas filled and normal in diameter.

Key take-home points
Make sure to include a left lateral in your abdominal radiographs! As you can see in this case, a rim of gas well-defines the pyloric material. In an empty stomach, the pyloric antrum should be filled with only gas in the left lateral projection.
