History of poorly differentiated sinonasal carcinoma SNUC s/p CRT. The patient also has a history of ankylosing spondylitis with sacro-iliac fusion and evidence of a C5-6 impingement. There is diffuse mild congenital narrowing of the cervical spinal canal. There is flowing anterior syndesmophyte formation at multiple lower cervical and imaged thoracic vertebrae. There is degenerative spondylosis of the cervical spine that is most pronounced at the C5-6 level with areas of uncovertebral and facet hypertrophy. There is also a mild disc-osteophyte complex with resultant moderate to severe right-sided and moderate left-sided neural foraminal stenosis at this level, as well as mild indentation upon the spinal cord. The spinal cord otherwise displays normal signal. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The paravertebral soft tissues are unremarkable. There is no evidence of mass lesions in the cervical spine region. There is encephalomalacia in the right inferior cerebellar hemisphere.
1. Stigmata of ankylosing spondylitis, a congenitally narrow spinal canal, and superimposed cervical spine degenerative spondylosis that is most pronounced at the C5-6 level, where there is moderate to severe spinal canal stenosis, moderate to severe right and moderate left neural foraminal stenosis. 2. No evidence of metastatic disease in the cervical spine.3. Chronic right posterior inferior cerebellar artery territory infarct.
