Case 3.A, Axial trace diffusion-weighted image (5700/138 [TR/TE], b = 1000 s/mm2) obtained 24 hours after the onset of symptoms shows bilateral thalamic areas of high signal intensity (white arrows) compatible with that of acute paramedian thalamic infarcts... Case 3.A, Axial trace diffusion-weighted image (5700/138 [TR/TE], b = 1000 s/mm2) obtained 24 hours after the onset of symptoms shows bilateral thalamic areas of high signal intensity (white arrows) compatible with that of acute paramedian thalamic infarcts.B, Axial T2-weighted image (5800/99/1 [TR/TE/NEX]) shows rounded areas (arrowheads) of increased signal intensity in the medial thalami.C, Axial T1-weighted (440/17/1 [TR/TE/NEX]) postcontrast image obtained 12 days after image in panel A shows contrast enhancement in the bilateral thalamic infarcts (black arrowheads).
