FIG 1. Case 1, a 69-year-old woman. MR images of the thoracolumbar spine, obtained 10 hours after sudden-onset severe back pain, show a large SEH in the dorsal area of T9–L3.

A, Sagittal T2-weighted (2000/80/2 [TR/TE/NEX]) image shows the hematoma as a heterogeneously hyperintense area (arrows).

B, Sagittal T1-weighted (400/20/2) image of the lumbar spine shows an isointense hematoma (arrowheads).

C, Contrast-enhanced sagittal T1-weighted image (400/20/2) shows an enhanced area (arrows) within the hematoma (arrowheads) at the level of T12.

D, Axial T1-weighted image (400/20/2), at the level of T12, shows an isointense hematoma (arrowheads).

E, Contrast-enhanced axial T1-weighted image (400/20/2), at the level of T12, shows an enhanced area (arrow) within the hematoma (arrowheads).
