The Sneddon syndrome is a rare clinical syndrome that associates strokes and livedo, etiologically related with the antiphospholipid antibody syndrome (Figure 1)11.

This 42 year-old woman with headache and right hemiparesis had a MRI that showed acute/ subacute ischemia in part of the territory of the left middle cerebral artery (MCA) and bi-hemispheric gliosis/ encephalomalacia (Figure 2). MR angiography showed normal cervical carotid and vertebral circulation, filling defect in M2 segment of the left MCA. Catheter angiography disclosed difuse cortical occlusive arteriopathy associated with a rich collateral cortical network. The M2 occlusion was reperfused, with infarct sign in its territory (Figures 3 and 4).
AXIAL FLAIR (A e B) showing areas corresponding to bi-hemispheric gliosis / encephalomalacia and area of acute/ subacute ischemic stroke in part of the territory of the left MCA. AXIAL DIFFUSION (C and D) proves acute / subacute schemic stroke area.
Angiography early arterial phase: (A) right side apparently normal; (B) slow filling area (red circle) and luxury perfusion (arrow).
