Case report. Hypoglossal palsy: computed tomography demonstration of denervation hemiatrophy of the tongue associated with glomus jugulare tumor.

In a patient with left glomus jugulare tumor and left hypoglossal nerve palsy, computed tomography demonstrated focal lucency of the left half of the tongue. This was interpreted to represent postdenervation fibrosis and fatty replacement of the intrinsic and extrinsic lingual muscles supplied by the hypoglossal (XIIth cranial) nerve.
