 There is mild motion limitation. The thoracic spine is in normal alignment, with a normal thoracic kyphosis. The vertebral body and disk heights are well maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber and signal. There is no pathological enhancement.There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the thoracic spine.The counting sequences again demonstrate partial visualization of the known expansile T2 hyperintense cystic appearing lesion centered at the C6 level with surrounding hemosiderin staining of the cord parenchyma. Prominent central spinal canal stenosis is noted along the mid cervical spine as there are superimposed spondylotic changes, with these findings detailed on prior dedicated MRI of the cervical spine.LUMBAR SPINE
1. Unremarkable MRI of the thoracic spine. No evidence of additional cord lesion, with partial visualization of previously described intramedullary lower cervical lesion.2. Questioned smooth enhancement along the cauda equina nerve roots, which may in part be artifactual/technical in nature. Confirmation of axial T1 post contrast images is limited secondary to artifact. However, the possibility of arachnoiditis is raised, and correlation with clinical history and CSF sampling is recommended.3. No significant spondylotic changes except for mild disk desiccation along the mid lumbar spine
