Sneddon syndrome – imaging findings
Síndrome de Sneddon – achados de imagem
The Sneddon syndrome is a rare clinical syndrome that associates strokes and livedo, etiologically related with the antiphospholipid antibody syndrome ([Figure 1])[1],[2],[3],[4],[5].
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]).
