Case Reports
[A case of isolated hypoglossal nerve palsy probably due to dural arteriovenous fistula].
We report here a case of isolated hypoglossal nerve palsy probably caused by dural arteriovenous fistula (DAVF). A 51-year-old woman was admitted to our hospital complaining headache, tinnitus, and tongue atrophy. Three years before, she first experienced right-sided pulsatile headache and tinnitus which persisted until admission. ⋯ Brain MRI was not remarkable. MRA and conventional angiography disclosed DAVF. We conclude that differential diagnoses for isolated hypoglossal paralysis should include DAVF.
