Imaging of PCNSV with lymphoma
Figure e-1. Imaging of a patient with primary CNS vasculitis associated with lymphoma.
(A) Cerebral angiogram shows stenosis of basilar artery and posterior cerebral arteries. (B) Diffusion-weighted magnetic resonance imaging (DWI) shows increased signal in several cortical and subcortical areas within the left parietal lobe and prerolandic area consistent with subacute ischemia. (C) Gadolinium T1-weighted MRI demonstrates areas of cortical enhancement within the left parietal lobe and prerolandic area due to blood-brain barrier damage.
Imaging of PCNSV without lymphoma
Figure e-2. Imaging of a patient with primary CNS vasculitis without lymphoma.
(A) Cerebral angiogram shows stenosis of the pericallosal segment of the anterior cerebral artery. (B) Diffusion-weighted magnetic resonance imaging (DWI) shows increased signal in the right brainstem consistent with subacute ischemia.
