An Indian runner duck ( Anas platyrhynchos domesticus ) was presented for a second opinion after a linear, metallic foreign body was identified on radiographic images. The primary veterinarian performed diagnostic imaging while investigating the presenting complaint of the duck's left pelvic limb lameness. The images obtained from a computed tomography scan performed during the second-opinion visit revealed a linear, metallic foreign body with an associated migration tract originating from the ventriculus and terminating in the proximal left femur. Significant osteomyelitis was noted at the proximal left femur associated with the presence of the linear, metallic object. The foreign body and the adhesions associated with its migration were removed in 2, staged, surgical procedures. Although penetrating ventricular foreign bodies have been previously reported, migration through the cortex of a long bone is an unusual presentation. This case demonstrates that perforating, migrating, gastrointestinal foreign bodies can result in lameness refractory to analgesia and ancillary supportive care.
