SUMMARY: An unusual case of venous congestive encephalopathy associated with cavernous sinus dural arteriovenous malformation is reported. The parenchymal changes consisted of a well-demarcated area of hyperintensity on T2-weighted MR images involving the cortex and underlying white matter in the ipsilateral temporal and posterior frontal region. It showed mass effect and persisted for 2 years before evolving into a venous infarction.
