Congenital Pedicle Hypoplasia of Lumbarized S1 Transitional Vertebra; A Rare Cause of Low Back Pain

摘要

We aimed to present radiological findings of a case of pedicle hypoplasia of lumbarized S1 vertebra accompanying with multiple vertebral and rib anomalies. Congenital aplasia or hypoplasia of spine pedicle is an uncommon anomaly. Aplastic- hypoplastic cervical, thoracal, lumbar pedicles have been reported. But sacral pedicle hypoplasia is rare anomaly. Sacral spine pedicle hypoplasia of lumbosacral transitional vertebra has not been reported previously in the radiological literature. Recognising of this anomaly can prevent misinterpretation of radiologic and clinical findings.
