Radiographic Diagnosis of a Rare Bifid Rib in a Cat

Abstract

A 7-year-old, 4.6 kg spayed female Korean short hair cat presented for health screening with occasional vomiting but had no significant medical history or remarkable clinical symptoms. Radiographic examination revealed bifurcation of the proximal part of the right 9th rib, extending into the caudo-ventral direction of the thoracic cavity without abnormalities in the vertebrae or other organs. This report highlights the importance of understanding radiographic findings and discusses the clinical significance of bifid ribs in veterinary medicine, especially during surgical procedures and trauma management. Advanced diagnostic imaging, including computed tomography, could provide potential valuable insights for detecting such rib anomalies and evaluating their significance. It is crucial that these types of rib anomalies are properly diagnosed in practice to ensure effective treatment and management. Further research into the genetic or developmental factors associated with rib anomalies in veterinary patients is recommended. © 2025, Korean Society of Veterinary Clinics. All rights reserved.
