This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. CT could precisely show and localize all niduses, and calcification was always detected. Lesions coming from the cervico-brachial plexus are expected to be found in more paraspinal locations. Aneurysmal bone cysts display cytogenetic rearrangements of the USP6 gene.
