Brain MRI imaging (3.0 T, T2 weighted) of patients 1, 2, and 3 with likely iPD and an isolated very large VR space in basal ganglia. Although most patients with widespread enlarged PVS remain asymptomatic, some develop neurological dysfunctions; however, it remains unclear whether these are the consequence of widespread enlarged PVS. 6. Since the brain lacks the lymphatic vessels found in peripheral tissue, these perivascular spaces act as a protolymphatic system and play a role in interstitial clearance. (B) Axial fluid-attenuated inversion-recovery images obtained at the same level showed that these areas have cerebrospinal fluid-like content. MRI performed in two unrelated boys aged 3 years with developmental coordination disorders revealed numerous intracerebral cysts strictly confined to one hemisphere, indicating unilateral marked widening of Virchow-Robin spaces.
