MR images (T2-weighted) on admission (Fig 1) detect a circumscribed right frontal area of parenchymal edema with leptomeningeal enhancement after Gd application (arrows).
Sequenced phlebograms of right internal carotid artery (Fig 2) reveal in the early venous phase (left) delayed local venous circulation with absence of a cortical frontal vein (arrow); the late venous phase (right) shows delayed appearance of the cortical vein with venous stasis (arrow).
1 month follow-up imaging (Fig 3) shows nearly complete reversal of venous parenchymal damage.
The venous ischemic lesions may be located cortical or subcortical and do not present any territorial similarity to the arterial ischemia. They appear to recover morphologically much more complete as the arterial ischemic lesions.
