case_images: Magnetic resonance imaging in a patient with primary progressive multiple sclerosis and features of brain interstitial space congestion. Imaging was performed before positioning a lumboperitoneal shunt. Multiple sclerosis lesions appear as round hyperintensities on coronary T2-weighted imaging obtained at the level of the third ventricle (black arrow). Enlarged perivascular spaces appear as linear hyperintensities crossing radially the Corona Radiata from the cortex to the ventricles (white arrow in higher magnification below). The size of the ventricles is normal.

case_images: T2-weighted brain MRI (Figure 1) performed in 2014 showed enlarged perivascular spaces as linear-, ovoid-, or round-shaped (depending on the slice direction) hyperintensities (Adams et al.,), associated with typical MS lesions (Wuerfel et al.,).
