Findings

MR T2-w or Flair

There is prominence of the Virchow-Robin spaces surrounding the cerebral perforatoring arteries or around the deep medullary veins, as often seen in the moyamoya vasculopathy.

There is increased T2 or flair signal following the Virchow-Robin spaces surrounding the cerebral penetrating white matter arteries or around the deep medullary veins, as often seen CNS angiitis and CNS microembolization.

There is minimally abnormal FLAIR in any site of positive diffusion imaging (implying stroke timeframe is recent <6 hours).

Given both the MR flair and the turbo spin-echo T2 are positive the ischemic event is beyond 8 hours

There is positive FLAIR in an arterial or dural sinus wall or lumen indicating the presence of residual acute thrombus.

Assess the T2 MR for optic hydrops (often requires multiplanar reformations).

There is evidence of early brain swelling or hemorrhage sufficient to produce evidence of brain shift and/or herniation.

There is evidence of early subependymal edema plus mild venticulomegaly indicating early stage of hydrocephalus.

Other

No other abnormalities are noted.
