Bifid Rib – Boon Or Bane




Bifid rib (BR), Vertebral defects, Gorlin Goltz syndrome


Bifid rib is a rare anatomical anomaly and it accounts for approximately 1.2 % of all the known rib abnormalities. The bifurcation usually occurs at the sternal end of the rib and its two extremities are joined to a bifid costal cartilage. These anomalies remain asymptomatic and can create misinterpretation during physical or radiological examinations. This case report provides a comprehensive summary about bifid ribs reported in the literature.
