Abstract

Isolated hypoglossal nerve palsy is a rare clinical condition and it causes deviation of the tongue and dysarthria. A 50-year-old female presented with tongue deviation to the left and mild dysarthria. She had no remarkable past medical history except several recent upper respiratory infections. On examination, the other cranial nerves were intact and she had no focal neurological signs. The findings of MRI and MR angiography were normal. Cerebrospinal fluid analysis revealed only mild elevation of protein. We diagnosed her as suffering with idiopathic isolated hypoglossal nerver palsy and we administered steroid therapy. The dysarthria was improved, but the tongue deviation still remained at 50 days after onset. We report here on a rare case of idiopathic isolated hypoglossal nerve palsy.
