We report a case of a posterior fossa arteriovenous fistula (AVF) with bith
alamic hyperintensity on MR images. The thalamic abnormality improved after
surgery, suggesting reversible venous hypertension as the pathogenesis of
the finding, as opposed to infarction. This manifestation of a posterior fo
ssa AVF should be considered in the differential diagnosis of bilateral tha
lamic disease.
