Figure

  • Fig. 1 Images of the radiation-induced vascular malformation and acute infarct in the pons. The vascular malformation was located principally on the right side of the mid-caudal pons, but its territory crossed the midline, involving the path of the left paramedian branch from the basilar artery. It had combined features of cavernoma, venous malformation, and capillary telangiectasia: with a dense hemosiderin deposit presenting as a hypointense lesion with a blooming effect, which appeared larger on a susceptibility-weighted image (arrow in A) than on a T2-weighted axial image (arrow in B); dystrophic calcification on a noncontrast CT axial image (arrow in C); a dilated draining vein on a contrast-enhanced T1-weighted sagittal image (arrow in D); and clustered dilated capillaries irregularly intervening in brain parenchyma on contrast-enhanced T1-weighted sagittal and axial images (arrowheads in D and arrows in E). An acute infarct located just left of and posterior to the preexisting vascular malformation was evident on a diffusion-weighted axial image (arrow in F).
