Article Figures & Data
Figures
- FIG 1.
Initial noncontrast head CT images demonstrate hypodensities in the left posterior parietal (black arrows) and peritrigonal regions as well as the corpus collosum (white arrows). No evidence of hemorrhage, mass effect, or midline shift is seen at this time.
- FIG 2.
Subsequent head CT demonstrates hemorrhage (white arrows) within the previously seen hypodensities. The posterior corpus collosum is involved.
- FIG 3.
Multiple diffusion-weighted images demonstrate restriction centered in the corpus collosum (white arrows), with some additional areas in the adjacent deep white matter including the centrum semiovale. In addition, there is faint diffusion restriction in the left occipital and temporal lobes, possibly representing subacute strokes. The thalami, brain stem, and cerebellum are spared.
- FIG 4.
A, Sagittal T1. Hypointense signal within the corpus collosum, most prominent in the splenium. B, Axial T2* sequence. Multiple punctate hypointensities compatible with hemorrhages are present within the corpus collosum (white arrow) and optic radiations, which are not shown. Axial (C) and coronal (D) T2 FLAIR. Increased T2 signal is seen with the corpus callosum (black arrows).
