- Figure 1 T2-Weighted and Postgadolinium T1-Weighted MRI Patterns in Various Myelopathy Diagnoses (Part 1)
A T2 hyperintense lesion (arrows) on sagittal MRI (A.a) displaying anterior predominant gray matter involvement (arrows) on cross section (A.b) with a typical craniocaudal linear strip (arrow) of enhancement (A.c) and more defined owl eye enhancement pattern (A.d, arrows) seen in anterior spinal artery infarct. A T2 hyperintense lesion (arrows) on sagittal MRI (B.a) spanning the entire cross-sectional area (arrow) of the spinal cord (B.b) with linear enhancement (B.c, arrow) in a pattern following the lateral columns (B.d, arrows) seen in paraneoplastic myelopathy. A compressive myelopathy highlighting an area of T2 hyperintensity (C.a-C.b, arrows) with an associated transverse band of pancakelike enhancement (arrows) just below the maximal area of stenosis (C.c) with sparing of the axial gray matter (C.d, arrows) seen in spondylotic myelopathy. Longitudinally extensive T2 hyperintense lesions (D.a, D.b, E.a, E.b, arrows) with extensive dorsal subpial enhancement (arrows) alone (D.c, D.d) or in combination (E.c, E.d) with central canal enhancement (arrowheads) forming the shape of a trident (E.d) seen in patients with sarcoid myelopathy.
- Figure 2 T2-Weighted and Postgadolinium T1-Weighted MRI Patterns in Various Myelopathy Diagnoses (Part 2)
A longitudinally extensive T2 hyperintense transverse myelitis (A.a-A.b, arrows) with associated elongated ring/partial ring enhancement (A.c-A.d, arrows) seen in AQP4-IgG NMOSD. A longitudinally extensive T2 hyperintense lesion (B.a-B.b, arrows) with an associated rim (arrows) and flame (arrowheads) pattern of enhancement surrounding a less enhancing center (B.c-B.d) seen in spinal cord intramedullary metastasis. Diffuse T2 hyperintensity (C.a-C.b, arrows) with apparent flow voids predominantly along the dorsal cord surface (C.a) and a missing piece of enhancement (C.c, arrow) in spinal dural arteriovenous fistula. Nonspecific T2 hyperintensity (D.a-D.b, arrows) and faint nonspecific contrast enhancement (D.c-D.d, arrows) seen in a patient with MOG-IgG associated myelitis. A T2 hyperintense expansile lesion (arrows) with mass effect (arrowhead) (E.a-E.b) and no clear pattern of associated contrast enhancement (E.c-E.d, arrows) seen in a patient with spinal cord ependymoma.
