Segmental costovertebral anomaly presenting with horn-like appearance in the chest.

Several types of abnormalities of the ribs have been reported. Many of these anomalies usually result in the correct diagnosis thanks to the characteristic radiological appearances. But some of the anomalies are rare and it is important to recognize and get accustomed to differing appearances of these osseous abnormalities in order to differentiate the pathological processes and to diagnose the syndromes which may accompany rib anomalies. The localized costovertebral anomaly with horn-like appearance, which has not yet been described in literature, is presented in this paper.
