Answer to the letter to the editor: 'A case of cervical pneumorrhachis induced by the combination of pneumomediastinum and root avulsion injuries' concerning 'Pathogenesis, diagnosis and management of pneumorrhachis' (by M. Oertel et al.).

摘要

We greatly appreciate the interest the authors have shown in our article on pathogenesis, diagnosis and management of pneumorrhachis . The pathophysiology and aetiologies of pneumorrhachis are known to be multifold with intraspinal air being almost always associated with further air distributions in other parts of the body . Nevertheless, the occurrence of pneumorrhachis secondary to pneumomediastinum has rarely been reported and the coexistence of spinal and mediastinal emphysema with nerve root avulsion injuries is an exceptional finding. Only one case of pneumorrhachis associated with pneumomediastinum and root avulsion of nerve plexuses was previously described .
