Obstructive hydrocephalus secondary to enlarged Virchow-Robin spaces: A rare cause of pulsatile tinnitus.
Obstructive hydrocephalus secondary to enlarged Virchow-Robin Spaces (VRS) is a rare entity, with only a few cases reported in the literature. Presenting symptoms vary widely from headaches to dizziness. ⋯ This is the first case of obstructive hydrocephalus secondary to enlarged VRS, presenting with pulsatile tinnitus.

The purpose of this study was to examine the safety and efficacy of target embolization of aneurysms associated with ruptured brain arteriovenous malformations (BAVMs). ⋯ Target embolization of aneurysms associated with ruptured BAVMs could significantly decrease postoperative rehemorrhage without increasing complications.

Full visualization of the aneurysm neck is usually impossible in a classical pterional craniotomy when a paraclinoid aneurysm is located on the opposite side of the internal carotid artery. Optic nerve (ON) retraction is required for better aneurysmal exposure, but ON injuries may occur. ⋯ With the advantage of a hybrid operating room, we introduced a novel technique to define the margins of the obscured aneurysm neck more clearly by obtaining a 3D-RA dual-volume reconstruction image to locate the aneurysm neck relative to a localization clip. This technique facilitates the clipping procedure and also reduces the risk related to ON retraction during surgical exposure of a paraclinoid aneurysm.

The aim of this study was to explore the association between cathepsin K and the clinical characteristics of skull base chordoma (SBC). ⋯ Increased cathepsin K expression in SBC was associated with tumor invasion and reduced PFS. The cathepsin K level in SBC also was associated with tumor stage, tumor lobulation, and septa.

Recent studies have reported the use of stent-assisted coiling (SAC) for wide-necked aneurysms in patients with acute subarachnoid hemorrhage (SAH). This study attempted to determine whether it is safe and efficient to use SAC for wide-necked aneurysms during post-SAH days 4-10. ⋯ Patients with ruptured wide-necked aneurysms treated on posthemorrhage days 4-10 did not appear to have worse outcomes compared to patients treated on posthemorrhage days 0-3.
