FIG 2. MR image of the patient’s head obtained on hospital day 12, 1 day after maximum hypernatremia, and within 24 hours of onset of tetraplegia.
A, FLAIR image (TR, 11,002; TE, 140; NEX, 1) is normal, as were proton density–and T2-weighted spin-echo images (not shown).
B, An abnormally hyperintense finding is present within the central pons on the isotropic DWI obtained with a b value of 1000.
C, There little change noted on the echo planar image obtained at b = 0.
D, The ADC map shows that hyperintensity at DWI does indeed represent restricted diffusion. (See Figure 1 for quantitative ADC results.)
