Figure 1. A 72-year-old female patient with
a left partial anterior circulation infarct. A, On
transverse T1-weighted volumetric isotropi-
cally reconstructed turbo spin echo acquisi-
tion images, an eccentric, focal lesion was
found in the P2 segment of the left posterior
cerebral artery (arrow). Also, an eccentric,
focal lesion (arrow in B) was observed in the
basilar artery without causing luminal steno-
sis (arrow in C). C, Transverse time-of-flight
magnetic resonance angiography shows an
asymptomatic stenosis of the P2 segment at
the same location as the vessel wall lesion
(arrow).
