Clinical question: Multiple sclerosis; follow-up progression. Signs and symptoms: Leg weakness. Nonenhanced thoracic MRI:Examination demonstrates fairly extensive patchy foci of/T2 STIR hyperintensity throughout the thoracic cord with evidence of regions of mild cord decreased caliber. The very large number of lesions as well as lack of intravenous contrast injection makes precise comparison with prior study difficult. Within this limitation however there is no convincing evidence of recurrent interval progression of disease.Signal intensity and anatomical alignment of vertebral column remains within normal. There is no evidence of a spinal canal compromise or stenosis at any level. There is also no evidence of any significant neural foraminal compromise at any level. No detectable. Spinal soft tissue abnormalities.
1.Extensive changes of demyelinating disease throughout the thoracic cord and with decreased cord caliber as detailed.2.The extent of disease appears similar to prior exam, however large number of lesions and lack of intravenous contrast precludes precise comparison with prior study.
