Patient 2: CNS vasculitis in a 37-year-old woman with systemic lupus erythematosus. Patient 2: CNS vasculitis in a 37-year-old woman with systemic lupus erythematosus. A, Axial SE MR image (3000/90) shows infarcts in the right cortical gray matter and subcortical white matter (MCA distribution, upper arrow; MCA/PCA watershed distribution, lower arrow). B, Axial SE MR image (3000/90) shows infarcts in the left cortical gray matter and subcortical white matter (PCA distribution, arrow). C, Angiogram of the left internal carotid artery shows areas of stenosis in the ACA, MCA, and PCA distributions (arrowheads). D, Angiogram of the right internal carotid artery shows lesions in the ACA (pericallosal) (arrowheads) and severe narrowing of the distal MCA (arrow). Note abnormal bilateral ACAs without corresponding MR abnormality. The MR image was obtained 7 days before the angiogram. Martin G. Pomper et al.
