Figure 1.

FLAIR and T2* sequences in a patient with an arteriovenous malformation. (a) Axial fluid-attenuated inversion recovery (FLAIR) sequence showing hypersignal in the left temporal lobe. (b) Axial T2* sequence showing mild hyposignal in the same area suggestive of bleeding. (c) Different section of the axial FLAIR sequence showing hypersignal surrounded by hyposignal. Bleeding cannot be confirmed. (d) Axial T2* sequence clearly showing hyposignal lateral to the left putamen. The patient has bleeding from the arteriovenous malformation.
