A 3-year-old patient with two episodes of remitting unilateral ophthalmoplegia ultimately was found to have nasopharyngeal rhabdomyosarcoma, despite initially negative results from neuroradiological and rhinological studies. While remitting superior orbital fissure syndrome has been ascribed to inflammation, this clinical picture has also been noted with masses such as aneurysm, chordoma, craniopharyngioma, and sarcoma.
