case_images: MRI of the thoracic spine in sagittal and axial views at the levels of T6-T7.. A = sagittal view; B = axial view; I = initial presentation; II = day 14th after diagnosis; III = week 11th after diagnosis. The regression of the canal stenosis over time from initial presentation to following up can be appreciated on the sagittal view (red arrow) as well as on axial images (red arrow). The reduction of the lesion size can be appreciated on the axial images (blue arrow).

case_images: MRI of the thoracic spine with/without contrast showed extension of enhancing masses into the spinal canal at the levels of T2-T12 (Figure 1). MRI of the thoracic/lumbar spine repeated 2 weeks after the initial imaging showed significant reduction in mass effect on spinal cord and decreased spinal canal stenosis (Figures 1 and 2). Nine weeks after discharge, repeat MRI of the thoracic/lumbar spines showed no cord compression or spinal stenosis (Figures 1 and 2).
case_images: MRI of the lumbar spine in sagittal and axial views at the levels ofL5-S1.. A = sagittal view; B = axial view; I = initial presentation; II = day 14th after diagnosis; III = week 11th after diagnosis. The images show regression of the central spinal canal stenosis: from near-complete-obliteration on the initial image (B.II.1 red arrow) to the subsequent re-emergence of the spinal canal (B.II.2 and B.II.3 green arrow) with medical treatment. Also noted is the decrease in size of the bony masses and is the most prominent in the sacral region (II.A images blue arrow).

case_images: MRI of the lumbar spine with/without contrast showed prominent medullary expansion of the visualized bony pelvis with associated extension of enhancing mass into the lumbar spinal canal at L5 level causing severe central spinal stenosis and neural foramen narrowing at levels of L5-S1 (Figure 2). MRI of the thoracic/lumbar spine repeated 2 weeks after the initial imaging showed significant reduction in mass effect on spinal cord and decreased spinal canal stenosis (Figures 1 and 2). Nine weeks after discharge, repeat MRI of the thoracic/lumbar spines showed no cord compression or spinal stenosis (Figures 1 and 2).
