Abstract
INTRODUCTION Progressive multifocal leukoencephalopathy is a rare but often fatal complication of some multiple sclerosis treatments. Although it has mainly been associated with natalizumab treatment, its appearance with other immunosuppressive therapies has also been reported. AIMS The aim of this case report is to describe the development of progressive multifocal encephalopathy in a patient with relapsing-remitting multiple sclerosis treated with ocrelizumab without previous use of natalizumab. CONCLUSIONS A summary of the presentation and disease course is provided, presented in the context of the current literature and likely pathophysiology.

Abstract
BACKGROUND AND PURPOSE The quantification and clinical significance of WD in CSTs following supratentorial stroke are not well understood. We evaluated the anisotropy by using DTI and signal-intensity changes on conventional MR imaging in the CST to determine whether these findings are correlated with limb motor deficit in patients with MCA ischemic stroke. MATERIALS AND METHODS We studied 60 patients within 12 hours of stroke onset. At admission, day 3, and day 30 of evolution, patients underwent multimodal MR imaging, including DTI sequences. We assessed the severity of limb weakness by using the motor subindex scores (5a, 5b, 6a, 6b) of the m-NIHSS and established 3 groups: I (m-NIHSS scores of 0), II (m-NIHSS, 1-4), and III (m-NIHSS, 5-8). FA values and rFAs were measured on the affected and the unaffected CSTs in the pons. RESULTS FA values for the CST were significantly lower on the affected side compared with the unaffected side only at day 30 (P < .001), and the rFA was significantly correlated with the motor deficit at day 30 (P < .001; r = -0.793). The sensitivity, specificity, and positive and negative predictive values for motor deficit by rFA < 0.925 were 95.2%, 94.9%, 90.9%, and 97.4%, respectively. CONCLUSIONS WD in the CST revealed by DTI correlates with motor deficit 30 days after MCA ischemic stroke. This study highlights the utility of imaging follow-up at 30 days and the potential of DTI as a surrogate marker in clinical trials.

Abstract
BACKGROUND The high morbidity and mortality of strokes result in enormous costs to our society. In the last decade advanced imaging techniques with high sensitivity in the diagnosis of acute stroke have been developed. Acute thrombolytic treatment beyond 3 h of acute stroke duration requires the demonstration of penumbra or 'tissue at risk'. However, the utility of the mismatch concept to identify the penumbra area is controversial. OBJECTIVE The aim is to describe the main features of acute stroke on magnetic resonance imaging. METHOD Information was obtained from a search of the PubMed and Medline databases (keywords: imaging, stroke, diagnosis and infarct) for articles published from 1997. CONCLUSION To conclude, new imaging biomarkers of relevant mismatch, hemorrhagic transformation and worse outcome should be developed in the future.
