Developmental delay and lack of expected normal physiological development in childhood. The cortical sulci are in proportion to the cerebral ventricles. Prominent perivascular spaces are demonstrated in the bilateral parietal lobes, right greater than left. No midline shift or mass effect is appreciated. The gray-white matter junction is preserved. There is no diffusion restriction to suggest acute ischemia. No abnormal gradient susceptibility is demonstrated. No intra-axial or extra axial fluid collections are visualized. Myelination appears appropriate for age.
Prominent perivascular spaces in the bilateral parietal lobes, right greater than left, are nonspecific and may be an incidental finding. However rounded appearance of some especially can be associated with mucopolysaccharidosis. Please correlate clinically.
