Reticular foreign bodies. Causative or coincidence?

A radiographically identified penetrating reticular foreign body is a near-certain cause of traumatic reticulitis, parareticular abscessation, or peritonitis. An extrareticular wire or nail is the most likely cause of reticulitis or peritonitis in an animal with compatible clinical signs. An immobile reticular foreign body may be trapped in the reticular mucosa, penetrating a mucosal fold (but not the reticular wall), or piercing the wall of the reticulum.
