Small intestinal enterolith in a dog presenting for a suspected gastric foreign body.

ABSTRACT

A 12-year-old Labrador Retriever presented for an acute onset of anorexia and vomiting. Abdominal ultrasound and abdominal radiographs were performed, and on the latter a large mineral opaque structure with concentric rings within the cranial abdomen was diagnosed as a gastric foreign body. Laparotomy revealed that the suspected gastric foreign body was a large enterolith within the small intestines. Enteroliths should be considered as one of the differential diagnoses for a large mineralized abdominal structure in a dog presented for gastrointestinal clinical signs.
