Abstract
INTRODUCTION: We report a case of a transient monocular altitudinal hemianopia associated with ethmoid mucocele. METHODS: A 34-year-old man presented with an episode of superior altitudinal hemianopia in the left eye that had lasted for about 10 minutes and then spontaneously improved three weeks ago. RESULTS: Humphrey visual fields showed normal visual field in both eyes. Exophthalmometry showed 18 mm in the right eye and 18.5 mm in the left. Magnetic resonance imaging of the orbit revealed a 2.5 cm-sized left posterior ethmoid mucocele. CONCLUSIONS: To the best of our knowledge, this may be the first report of mucocele associated with transient altitudinal hemianopia. The described findings may facilitate the diagnosis of mucocele in patients who present with a monocular altitudinal hemianopia.
