Note.—F indicates female; M, male; S + D, stenosis with dilation; S, stenosis without dilation; Ope, discoloration of affected artery around aneurysmal dilation due to intramural hematoma seen during operation; DL, double lumen sign seen on cerebral angiograms; IMH, hyperintensity around signal void due to intramural hematoma seen on T1-weighted MR images; VS, vegetative state; MD, moderate disability; GR, good recovery.
* Four cases showed ischemic symptoms and CT evidence of slight subarachnoid hemorrhage on initial CT scans.
† In 4 cases, the double lumen sign was seen on follow-up angiography.
