title: A case report of unilateral hypoglossal neuroparalysis resulting from horizontal subluxation in the atlanto-occipital joint due to rheumatoid arthritis.
abstract: We experienced a case of unilateral hypoglossal neuroparalysis, in which the right hypoglossal nerve was compressed by horizontal subluxation in the atlanto-occipital joint, due to rheumatoid arthritis. This report represents a very rare case of unilateral hypoglossal neuroparalysis, in which diagnostic imaging of CT with multiple cross-sectional images (three-dimensional CT) was quite useful for the identification of compression by horizontal subluxation.
