Figure 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.
