This systematic review and meta-analysis aimed to determine whether the presence of IVLs and CN VIII NVC on MRI is associated with tinnitus, SNHL, or vertigo and any specific subtypes. It was found that CN VIII NVC is associated with vestibular paroxysmia, and IVL is associated with sudden-onset SNHL. No association was found between IVL or CN VIII NVC and undefined tinnitus, SNHL, and vertigo.

This comprehensive review of cortically based brain tumors in children proposes a decision tree to help with the differential diagnosis.

A DSA-based flow quantification tool (AneurysmFlow) was used to measure blood flow vectors and velocities after contrast injection. Complex flow patterns were shown to be common in ruptured aneurysms and those with daughter sacs. Lowest mean aneurysm flow amplitude in the dome and daughter sacs indicated pathophysiologic changes linked to rupture. Also, hypertension, bifurcation location, and irregular shape of unruptured aneurysm were found to be independent rupture risk factors.
