A 48-year-old woman presented with a growing palpable mass at the left frontal area. The imaging studies and histopathological examination of the mass was consistent with dural-based Rosai-Dorfman disease with unusual transcranial extension. We reported this case not only because of its rarity, but also because of the infiltrative pattern. The infiltrative nature presented in this case may be taken into consideration for surgical treatment of intracranial Rosai-Dorfman disease.

Multicenter Study Clinical Trial
Intra-arterial tenecteplase for treatment of acute ischemic stroke: feasibility and comparative outcomes.
Tenecteplase (TNK) is a third-generation thrombolytic agent. We evaluated the safety and feasibility of intra-arterial (IA) administration of TNK in patients with acute ischemic stroke. ⋯ Our study demonstrates that administration of IA TNK in acute stroke is safe and results in rates of favorable outcomes that are comparable to those observed with currently used drugs. Additional studies are needed to further determine the safety and efficacy of IA TNK in acute stroke treatment.

Previous imaging studies in the Machado-Joseph disease (MJD/SCA3) have mostly concentrated on the cerebellum and brainstem. Our goal was to perform a whole brain longitudinal evaluation. ⋯ We confirmed cortical involvement in MJD/SCA3. The most important factors in predicting GMD were age and CAG. The lack of progression of atrophy may indicate floor effect and/or short duration of follow-up.

Comparative Study
Determination of language dominance: Wada test and fMRI compared using a novel sentence task.
This study aimed to develop a new linguistic based functional magnetic resonance imaging (fMRI)-sentence decision task that reliably detects hemispheric language dominance. ⋯ The sentence task provides robust activations in putative essential language areas and can be used for visual analysis of predefined areas to facilitate interpretation of clinical fMRI.

To evaluate the time periods of Wallerian degeneration (WD) in which the diffusion parameters of ipsilateral corticalspinal tract (CST) can be used to predict the motor function outcome after brain infarction. ⋯ The rFA and ipsilateral FA values after 2 weeks of stroke onset correlate with the motor function outcome.
