Transient oculomotor palsy after influenza vaccination: short report

Several neurological complications have been described after influenza vaccination. Oculomotor palsy has not been yet related with influenza vaccine. We report a 79-year-old man who developed an acute transient right oculomotor palsy two days after a routine influenza vaccination, for which no other cause was identified. There was no evidence of diabetes, glucose intolerance, high blood pressure, hipercholesterolemia, smoking, obesity, systemic vasculitis, or other risk factor for ischemic neuropathy. The cerebrospinal fluid was normal as well as the MRI and MRA scans. The differential diagnosis and the possible relationship between the vaccine and the oculomotor palsy are discussed.
