Computed tomography in acquired absence of thoracic pedicle

CT findings in tuberculous spondylitis

The computed tomographic (CT) features of ten documented cases of spinal tuberculosis were analyzed. All cases showed evidence of vertebral body destruction, with paravertebral soft tissue masses. Four cases revealed extension of involvement into the neural arches. Calcification within the paraspinal soft tissue was found in only two cases. Two of four cases who received intravenous contrast medium demonstrated evidence of rim enhancement around multilocuated fluid collections. Compared to conventional roentgenography, CT better delineated the extent of bony destruction, involvement of the spinal canal and existence of paraspinal soft tissue masses.

Hypoplasia of thoracic pedicle: CT diagnosis. A case report with emphasis on CT diagnosis

A rare case of hypoplasia of a left pedicle of T11 is reported. The contribution of computed tomography to assess the diagnosis and display the eventual associated malformations of the neural arch is discussed.

Congenital absence and hypoplasia of pedicles in the thoracic spine

A case of thoracic pedicle aplasia of T12 coincident with pedicle hypoplasia at T11 is reported. The authors review the literature on thoracic pedicle deficiency and discuss the computed tomography (CT) findings in the thoracic pedicle aplasia/hypoplasia spectrum.
