To assess the safety and efficacy of vertebral artery origin angioplasty and stenting for stroke prevention in a multicenter clinical experience. ⋯ Endovascular intervention of VAOS is associated with low peri-procedural complication rates. Restenosis remains a concern; age and smoking predicted future restenosis.

Diffusion anisotropy color-coded maps of cerebral white matter can be generated from orthogonal anisotropic diffusion-weighted imaging (DWI) using the three-dimensional anisotropy contrast (3DAC) technique, but its precision has not been fully validated. Hence, we attempted to determine whether 3DAC is comparable to a diffusion tensor imaging (DTI) color map. ⋯ The 3DAC could visualize directional information of white matter tracts as precisely DTI-based color maps did, particularly when FA was large and/or e1 directions were orthogonal.

High core body temperatures have been shown to selectively damage the cerebellum and basal ganglia in malignant hyperthermia, but involvement of both areas in neuroleptic malignant syndrome (NMS) has not been described. ⋯ Both the basal ganglia and cerebellum can be injured selectively in NMS.

Isolated focal common carotid artery dissection is a rare condition. ⋯ Focal isolated common carotid artery dissection is a rare condition not to be overlooked. This case presents an incidental finding possibly of traumatic nature. In the presence of concomitant migraine its causal embolic relation to the transient word-finding difficulties must remain open.

Diagnosis of tibial neuropathy has been traditionally based on clinical examination and electrodiagnostic studies; however, cross-sectional imaging modalities have been used to increase the diagnostic accuracy and provide anatomic mapping of the abnormalities. In this context, magnetic resonance neurography (MRN) offers high-resolution imaging of the tibial nerve (TN), its branches and the adjacent soft tissues, and provides an objective assessment of the neuromuscular anatomy, abnormality, and the surrounding pathology. This review describes the pathologies affecting the TN and illustrates their respective 3 Tesla (T) MRN appearances with relevant case examples.
