Case Reports
Magnetic resonance characteristics and susceptibility weighted imaging of the brain in gadolinium encephalopathy.
To report the brain imaging features on magnetic resonance imaging (MRI) in inadvertent intrathecal gadolinium administration. ⋯ Intrathecal gadolinium demonstrates characteristic imaging features on MRI of the brain and may mimic subarachnoid hemorrhage on susceptibility-weighted imaging. Identifying high dose gadolinium within the CSF spaces on MRI is essential to avoid diagnostic and therapeutic errors.

Comparative Study Controlled Clinical Trial
Brain atrophy in radiologically isolated syndromes.
The aim of this study was to compare brain atrophy in radiologically isolated syndrome (RIS), in clinically isolated syndrome (CIS), and in individuals with subjective complaints (ISC). ⋯ NTBV and NCV were significantly lower in RIS compared with ISC while no differences were observed in NWMV.

Studies on Whites and Asians have shown contradictory results on the association between an incomplete circle of Willis (CoW) and white matter disease (WMD). We evaluated such relationship in Ecuadorian Mestizos. ⋯ In the Ecuadorian Mestizo population, WMD occurrence and severity do not seem to be related to incompleteness of the CoW.
