Reason: lesion History: history of NMO The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. Since the prior exam T2 signal hyperintensity previously noted from approximately C3 down to T8 to 3 disk space level has a regressed and is not readily identified. At the edge of the film at the C7 vertebral body level there appears to be right hemicord signal hyperintensity on T2 imaging which is not completely included on this exam. At the T9 T10 disk space level there is right hemicord signal hyperintensity on T2 imaging.
1.Since the prior exam thoracic spinal cord lesion extending from me cervical spinal cord has regressed.2.There is a right hemi-cord lesion present in the C7 level which is not completely included on this exam. Perhaps an MRI of the cervical spine with help further assess this lesion. The possibility of demyelination cannot be excluded.3.There is a lesion present in the right hemicord at T9-10. The possibility of demyelination cannot be excluded.
