Splenic abscesses due to migrant metallic wires from small intestine in a horse

This reports discusses a perforating metallic wire that was suspected of causing chronic weight loss, inappetance and pyrexia in a 15-year-old Standardbred gelding, due to the fact that during the previous 18 months, 6 horses coming from the same yard were referred for recurrent or acute colic related to the ingestion of metallic wires. Splenomegaly was detected ultrasonographically and confirmed during surgery. During necropsy, 2metallic wires 0.2 mm in diameter and 3–4 cm long were found in a markedly enlarged spleen with several nonencapsulated abscesses. Metallic wire perforation and migration through the lower alimentary tract may involve different abdominal quadrants (intestine, abdominal wall, spleen, liver) and lead to different clinical syndromes as acute or recurrent colic and weight loss. A clinical diagnosis is challenging as the symptoms are often nonspecific and prognosis is generally considered poor.
