Fig 6. Patient with an occipital AVM. Procedure-related technical events occurred during treatment (reflux of glue and a glued catheter).

A, Axial CT performed the day after treatment illustrates the severe artifacts caused by the glue, but no obvious ischemic lesion is noted.

B and C, Corresponding sections on postprocedural MR-DWI/ADC demonstrate a rather large ischemic lesion (arrows) within the left thalamic nucleus (not seen on the CT image).

D, Axial T2-weighted MR image at follow-up shows a small and permanent infarct in the posterior portion of the left thalamus (arrowhead).
