Emissary veins connect the extracranial venous system with the intracranial venous sinuses. These include, but are not limited to, the posterior condyloid, mastoid, occipital, and parietal emissary veins. ⋯ Detailed descriptions of these venous structures are lacking in the literature, and, to the authors', knowledge, this is the first detailed review to discuss the anatomy, pathology, anomalies, and clinical effects of the cranial emissary veins. Our hope is that such data will be useful to the neurosurgeon during surgery in the vicinity of the emissary veins.

Vein of Galen malformations in neonates: new management paradigms for improving outcomes.
Untreated patients with symptomatic neonatal presentation of vein of Galen aneurismal malformations (VGAMs) carry almost 100% morbidity and mortality. Medical management and endovascular techniques for neonatal treatment have significantly evolved. ⋯ Treatment of refractory heart failure in neonatal VGAM with modern prenatal, neurointensive, neuroanesthetic, and pediatric neuroendovascular care results in significantly improved outcomes with presumed cure and normal neurological development in most.

Carotid plaque characteristics influence future risk of stroke considerably. However, the severity of stenosis does not accurately reflect plaque burden in patients with expansive arterial remodeling. ⋯ Symptomatic low-grade carotid stenosis with vulnerable plaque confirmed by MRI was associated with a high rate of stroke recurrence that was refractory to aggressive medical treatment. However, carotid endarterectomy was safe and effective for such patients. Plaque characterization by MRI has the potential for more accurate stroke risk stratification in the management of carotid low-grade stenosis.

Achille Louis Foville's atlas of brain anatomy and the Defoville syndrome.
Achille Louis Foville's atlas of brain anatomy (1844) is one of the most artistic and detailed works on neuroanatomy in the medical literature. The outstanding drawings by the 2 artists, Emile Beau and Frédéric-Michel Bion, highlight all the philosophy, ability, and sensibility of A. L. ⋯ Through analyzing the political and scientific events in France in the 19th century, we highlight the invaluable contributions of A. L. Foville and his son to the history of neuroanatomy and neurology.
