[Isolated hypoglossal nerve palsy secondary to an atlantoccipital joint synovial cyst. Case report and literature review].
Hypoglossal nerve palsy is commonly associated with the involvement of other cranial nerves. His injury is rarely isolated. We present a patient in which paralysis is due to the presence of a "juxtafacet cyst" of the atlanto-occipital joint. We review the anatomy of the hypoglossal nerve, different therapeutic options, the differential diagnosis and papers published to date.
