Reversible multifocal leukoencephalopathy associated with a nocturnal blood pressure non-dipper pattern.
The majority of cases of leukoencephalopathy related to hypertensive crisis show brain lesions predominantly in the posterior lobe. Such cases are usually classified as reversible posterior leukoencephalopathy syndrome (RPLS). A multifocal distribution pattern is also possible, but occurs seldom. Here we report two patients with extensive white matter lesions that affect the entire brain, related to hypertensive crisis associated with a non-dipper pattern of blood pressure during the night as well as renal dysfunction. This nocturnal blood pressure abnormality may be relevant for the distribution pattern of cerebral white matter lesions and underlines the concept that in these cases a 24-h ambulatory blood pressure monitoring is needed.
