Case 2, an 82-year-old man. Case 2, an 82-year-old man. MR images of the cervical spine, obtained 4 hours after a fall, reveal a large SEH in the dorsal area of C5–C7.A, Sagittal T2-weighted (2000/80/2) image shows a hyperintense epidural hematoma (arrowheads). A hypointense displaced dura (arrows) indicates the epidural location of the hematoma.B, Sagittal proton density-weighted (2000/20/2) image shows a slightly hyperintense SEH (arrowheads).C, Sagittal T1-weighted (400/20/2) image reveals the isointense SEH (arrowheads).D, Contrast-enhanced sagittal T1-weighted (400/20/2) image shows multiple, enhanced spots (arrow) within the hematoma (arrowheads).E, Contrast-enhanced axial T1-weighted (400/20/2) image shows spotty enhancement (arrows) at the level of C6.
