Incomplete coil occlusion is associated with increased risk of aneurysm recurrence. We hypothesize that intracranial stents can cause flow remodeling, which promotes further occlusion of an incompletely coiled aneurysm. ⋯ Stent-assisted coiling causes progression of occlusion, possibly by a flow remodeling effect. The odds of progression of occlusion of stent-coiled aneurysms were 18.5 times that of nonstented aneurysms.

Magnetic resonance with diffusion tensor image (DTI) may be able to estimate trajectories compatible with subcortical tracts close to brain lesions. A limit of DTI is brain shifting (movement of the brain after dural opening and tumor resection). ⋯ The use of intraoperative DTI demonstrated brain shifting of the CST. DTI evaluation of white matter tracts can be used during surgical procedures only if updated with intraoperative acquisitions.

Case Reports
Successful anterior capsulotomy in comorbid anorexia nervosa and obsessive-compulsive disorder: case report.
State-of-the-art treatment of anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) often proves ineffective. Both disorders have common features, and anterior capsulotomy is a last-resort treatment for OCD. We document the effect of bilateral anterior capsulotomy in a patient with comorbid AN and OCD. ⋯ This case report suggests that bilateral anterior capsulotomy can be a therapeutic option for patients with comorbid AN and OCD. However, a well-controlled study is warranted.

Successful management of pediatric arteriovenous malformations (AVMs) often requires a balanced application of embolization, surgery, and radiosurgery. ⋯ Treatment of pediatric AVMs with multimodality therapy can substantially improve obliteration rates and may decrease AVM hemorrhage rates. The poor natural history and risks of intervention must be carefully considered when deciding to treat high-grade pediatric AVMs.

In cases of large and giant vestibular schwannomas (VS), the visualization of the internal auditory canal (IAC) opening is difficult or impossible. ⋯ The Tübingen line is an easy, consistent, and safe method to locate the projection of the IAC along the posterior surface of the temporal bone.
