Presentation
Known case of acute lymphoblastic leukemia (ALL); completed chemotherapy 1.5 years ago. The patient currently complains of mild lower limb weakness.
Patient Data
Multiple areas of altered signal are noted over the entire vertebral column, involving the posterior elements, with complete suppression on STIR and no post-contrast enhancement, likely suggestive of areas of fatty deposition which could be sequelae to marrow reconversion or post-treatment changes.
The spinal cord appears normal in signal intensity, with T1/T2 hypointense soft tissue seen surrounding the conus medullaris and cauda equina nerve roots within the thecal sac, with no significant post-contrast enhancement, likely suggestive of epidural fibrosis.
Case Discussion
Altered signal intensities getting completely suppressed on STIR without post contrast enhancement likely suggestive of marrow reconversion.
