• The two essential components of the paratrigeminal syndrome of Raeder are unilateral oculosympathetic paresis and evidence of trigeminal nerve involvement on the same side. Over the years, pervessions and classifications have followed, leading to confusion. Many unilateral vascular headaches associated with ipsilateral oculosympathetic paresis have been cited as examples of Raeder's paratrigeminal syndrome. In this communication, the original description of the syndrome will be reviewed, sources of confusion will be emphasized, and illustrative examples will be presented.
