Plain-English summary
Lameness, or difficulty walking, is a common reason for horses to stop competing or being active. The lower leg is often examined with advanced imaging techniques to help veterinarians tell the difference between normal issues and serious problems. In this case, a horse had a large cystic lesion, which is a fluid-filled sac, in a bone called the third phalanx (P3). This lesion caused a sudden fracture in the bone. The condition was thoroughly examined after the horse passed away using advanced imaging and tissue analysis.
Abstract
Lameness remains a common cause of retirement in the equine athlete and among hobby enthusiasts. The distal limb is one of the most frequently imaged areas, and recent advances in diagnostic imaging capabilities help practicing veterinarians differentiate normal variants from informative pathology. Although acute, non-weight-bearing lameness is commonly associated with etiologies, such as fractures, abscesses, and laminitis, other uncommon differentials such as cystic lesions and neoplasia might also be considered. This report describes the characterization of a large, cystic lesion in the third phalanx (P3), which resulted in an acute, pathologic fracture. The lesion was fully characterized with the use of postmortem magnetic resonance imaging, gross pathology, and histopathology.
