Case Reports
[Three cases demonstrating the characteristic neuroimaging of reversible posterior leukoencephalopathy syndrome].
Revisible posterior leukoencephalopathy syndrome (RPLS) is a syndrome defined predominantly by a characteristic pattern of MR images but heterogeneity and reversibility of the abnormalities is unclear. Three patients with characteristic neuroimaging of RPLS are described. Case 1. ⋯ She had left hemianopia and left hemiplegia 1 month later. This report has important implications concerning the accurate early diagnosis of RPLS using MRI including DWI and its utility in prompting initial treatment. It should be noted that some cases demonstrating the characteristic neuroimaging pattern of RPLS do not attain full recovery and that surgical intervention is required in some cases.

To determine whether monitoring facial nerve motor evoked potentials (FNMEPs) elicited by transcranial electrical stimulation during skull base tumor surgery is useful for predicting facial nerve outcome. ⋯ Intraoperative FNMEP monitoring is useful for predicting facial nerve function after skull base surgery.
