The influenza vaccination is associated with several neurological complications, namely cranial nerve neuropathies. There are only two clinical cases described in the literature of isolated glossopharyngeal and vagus nerve palsies after influenza vaccination. We report a case of glossopharyngeal and vagus nerve palsies four days after receiving an inoculation of the inactivated influenza vaccine, in an adult without a previous neurological history. Intravenous immunoglobulin (IVIg) treatment was applied and the symptoms quickly disappeared. The atypical manifestations of Guillain-Barré syndrome (GBS) can present with mild neurological deficits that are easily overlooked. In these cases, a careful assessment should be made, taking into account the risk of disease progression, the need for clinical surveillance and immediate immunological treatment, which improves the prognosis of the disease.
