Today’s case is a 10 year old female neutered Corgi with several days of vomiting and anorexia. What is the most important finding?
The liver is mildly enlarged with rounded margins. The stomach is mildly distended with fluid and gas. On the ventrodorsal projections, the duodenum is moderately distended with fluid and gas, with several unusual gas bubbles. There is a soft tissue-gas interface at the caudal duodenal flexure. The remainder of the small intestine is normal in diameter. A metallic sewing needle is present in the retroperitoneal space. No abnormalities are noted in the spleen or urinary tract. Radiopaque sutures are present in the ventral abdominal wall.
Duodenal foreign body (corn cob).
An ultrasound examination was performed to confirm the location of the foreign body. The duodenum was distended with fluid proximal to the clean-shadowing foreign object, and returned to normal diameter distal to it. A laparotomy was performed to remove both the foreign body and the sewing needle. The liver biopsy showed vacuolar hepatopathy.
