Most spine surgeons and anesthesiologists believe that the risk of spinal cord injury (SCI) during intubation is mainly due to mechanical compression of the spinal cord due to cervical spine movement in cases of undiagnosed but severe cervical lesions. With this reasoning, difficult intubation, which is more frequently encountered in patients with preexisting cervical diseases, is likely to result in SCI. Several reports have described SCI after non-cervical surgery in patients previously diagnosed with cervical myelopathy and a chronically compressed cervical cord; however, to date, there is less acknowledgement of SCI in patients with undiagnosed cervical myelopathy. Here, we report a painful experience of neurological deterioration that developed immediately after elective lumbar decompressive surgery in a 76-year-old man. The possible mechanism behind these unexpected complications is discussed in a review of the literature.

Although the exact etiology of the Andersson lesion (AL) remains unclear, it is known to occur mostly in patients with long-standing ankylosing spondylitis (AS). Among the various theories for the etiology of AL, repetitive trauma and inflammatory causes are the most common. The histopathological appearance of the AL in this report was consistent with that of chronic inflammation without any infection. Pyogenic ALs in the context of AS are extremely rare; to the best of our knowledge, positive cultures of this lesion in bone biopsies have never been reported. Herein, we report a rare case of a pyogenic AL with a positive culture and discuss a relevant review of the literature.
