title: Magnetic Resonance Myelography in Congenital Absence of the Cervical Pedicle.
abstract: Absence of the cervical pedicle is a very rare congenital anomaly, easily misrecognized as a unilateral facet dislocation in a setting of acute trauma or a neoplastic process like a nerve sheath tumor. Although correct diagnosis can be achieved on the cervical radiograph and confirmed by the CT, MRI Myelography is clearly of additional value because shows the specific relationship and orientation of the nerve roots. To the best to our knowledge, this is the first description of MR Myelography findings.
