Abstract

A case of unilateral tongue atrophy caused by idiopathic hypoglossal nerve palsy is presented.<BR>A 38-year-old woman noticed atrophy in the left side of the tongue and visited Hokkaido University Dental Hospital. The face was symmetrical, and there was neither facial nerve weakness nor muscle atrophy. The movement of the neck and brachium was not restricted. She had fasciculation and atrophy in the left side of the tongue. When the tongue protruded, it deviated towards the left. The shape and movement of the soft palate were normal. MRI examination revealed atrophy in the left side of the internal muscles of the tongue. The cranial nerves other than the twelfth nerve were normal, and there were no signs of systemic neurological abnormalities. Unilateral tongue atrophy caused by idiopathic hypoglossal nerve palsy was diagnosed.
