  • Description: Urgent magnetic resonance imaging (MRI) scan (Fig 2) of the lesion showed no post-gadolinium enhancement, no restricted diffusion, complete suppression of the cystic areas on T2 fluid attenuation inversion recovery (FLAIR) sequence and no abnormal parenchymal signal intensities compared with normal brain parenchyma. Magnetic resonance images showing tumefactiveperivascular space (arrows): (a) T2-weighted sequence; (b) T2 fluidattenuation inversion sequence with gadolinium showing completesuppression of fluid signal in the multicystic lesion; (c) T1-weightedsequence with gadolinium showing no enhancement; and (d) diffusionweightedimaging showing no restricted diffusion Dilated perivascular spaces (PVSs) in the brain are interstitial fluid-filled structures lined by pia-mater that have accompanying patent penetrating arteries within, most commonly seen along the lenticulostriate arteries.1 They can be unilocular or multilocular and may have a radial pattern along the course of the penetrating arteries. The mass effect of the tumefactive PVS may cause chronic ischaemic change in adjacent white matter.3 Histopathological results typically show a pial-lined cyst with no evidence of neoplasm or infection.
