FIG 3. Patient 8.
A, Initial sagittal T1-weighted image (400/14/3), obtained 48 hours after the onset of headache and neck pain that clinically was suspicious for subarachnoid hemorrhage, reveals an EDH at C2-C3 (arrowheads) that is isointense to spinal cord.
B, Sagittal T1-weighted image (733/20/2), obtained after the administration of contrast material, shows striking central enhancement.
C, Axial gradient-echo image (500/12/2; flip angle, 20°), obtained at the C5 level, shows minimal deformity of the spinal cord from the posterolateral EDH (arrowheads).
