Brown-Sequard syndrome produced by calcified herniated cervical disc and posterior vertebral osteophyte: Case report

Abstract Brown-Sequard syndrome (BSS) produced by cervical disc disorders has rarely been seen clinically and only 50 cases have been reported in English literatures. However, most of which have resulted from acute disc herniation. Here, we report a case of BSS produced by calcified herniated C4-C5 disc and posterior vertebral osteophyte, in which decompression through anterior approach was performed. This case revealed the potential of cervical spondylopathy leading to BSS in a chronic manner. Once the diagnosis is established, it is advisable to perform decompression as early as possible.
