Article Figures & Data
Figures
- Fig 1.
Summary of causation of myelopathy. Abbreviations: CC indicates cryptococcus; Zoster, Varicella zoster; MA, Mycobacterium avium; EC, enterococcus; and MEAS, measles; CMV, cytomegalovirus.
- Fig 2.
Tuberculous spondylo-diskitis. A, Sagittal T2-weighted MR imaging demonstrates caseous destruction of the L2–3 disk with epidural collection causing compression of the conus. B, Coronal FISP demonstrates large psoas abscesses communicating with the L2–3 disk. A thick walled collection displaces the right kidney superiorly.
- Fig 3.
Nonspondylitic spinal tuberculosis. A, T1 sagittal pregadolinium image with increased signal of the CSF. B, T2 sagittal shows root thickening. C and D, T1 sagittal postgadolinium demonstrates circumferential cord and root enhancement. E, T2 sagittal shows loculated CSF with extensive cord signal abnormality.
- Fig 4.
Burkitt lymphoma. A, Coronal FISP showing nonfluid-containing right L2/3 paraspinal and right pelvic masses infiltrating the right iliac bone and multiple low-signal lesions in both renal cortices. B, Sagittal T1 shows diffusely low marrow signal with isointense epidural masses posterior to the bodies of L5, S1, and S2.
- Fig 5.
Plasmablastic lymphoma. A, Axial T2-weighted MR imaging shows a large destructive lobulated mass in the left hemithorax infiltrating the thoracic spinal canal via the neural foramen. B, T2-weighted sagittal MR imaging showing posterior epidural cord compression.
- Fig 6.
EB-associated myopericytoma. A, Sagittal T2-weighted MR imaging shows predominantly low-signal epidural mass causing significant cord compression at T6/7 with abnormal marrow in the adjacent vertebral body. B, Coronal FISP demonstrates improved conspicuity of marrow signal abnormality. C, Axial T2-weighted image shows tumor displacing and compressing the cord.
