Presentation transcript:

A 48-year-old woman with acute myelogenous leukemia status post allogenic BMT had a seizure 19 days after transplantation. A 48-year-old woman with acute myelogenous leukemia status post allogenic BMT had a seizure 19 days after transplantation. Baseline blood pressure was 134/84 mm Hg, and blood pressure at toxicity was 132/48 mm Hg.A–B, Vasogenic edema is present in the occipital poles (open arrows) and thalamus (arrowheads) bilaterally along with deep white matter in the subinsular region (small arrow).C–D, Vasogenic edema is present in the parietal region (curved arrows) and corona radiata and subinsular region (small arrows) bilaterally and caudate nucleus on the left (arrowhead).E, Vasogenic edema is present in the parietal region (curved arrows) bilaterally with involvement along the superior frontal sulcus (large arrows) bilaterally. A linear “string-of-pearl” pattern is also present in the adjacent left centrum semiovale (small arrows). MR imaging is consistent with a more diminutive expression of the superior frontal sulcus pattern. W.S. Bartynski, and J.F.
