Venous Hypertension Associated with a Posterior Fossa Dural Arteriovenous Fistula:Another Cause of Bithalamic Lesions on MR Images AJNR 20:145-147, Greenough,G.P.,et al, 1999 See this aricle in Pubmed Article Abstract We report a case of posterior fossa arteriovenous fistua (AVF) with bithalamic hyperintensity or MR images. The thalamic abnormality improved after surgery, suggesting reversible venous hypertension as the pathogenesis of the finding, as opposed to infarction. The manifestation of a posterior fossa AVF should be considered in the differentiation diagnosis of bilateral thalamic disease.
