Headache, Confusion, and Seizures in Patient With SLE


C. Distribution of abnormalities confined to a single vascular territory

A typical finding in RPLS is symmetric white matter edema in the posterior cerebral hemispheres, particularly the parieto-occipital regions.1 The calcarine and paramedian parts of the occipital lobe are usually spared, helping to distinguish RPLS from bilateral posterior cerebral infarction.1 Involvement of the cerebellum and brainstem is common, and the distribution of abnormalities usually is not confined to a single vascular territory.

Because neuroradiographic findings after seizure or other neurologic conditions can be similar to those seen in RPLS, repeat neuroimaging may be necessary. With treatment, resolution of abnormal neuroimaging findings usually occurs within days to weeks.2
