IntroductionRoom tilt illusion is a distorted perception of the spatial distribution of objects due to complex rotations in different planes. This distortion usually occurs in the vertical plane and is usually associated to vertebrobasilar ischemia. The etiology of the phenomenon varies greatly and only rarely corresponds to migraine aura.Case ReportSince youth, a sixty-year-old woman had frequent episodes of room tilt illusion in the horizontal plane. These lasted from 30 minutes to 2 hours and were always followed by frontal headache fulfilling criteria for migraine (computerized tomography and magnetic resonance imaging) were normal. Visual symptoms and headache disappeared following treatment with flunarizine.DiscussionRoom tilt illusion might be a rare symptom of migraine aura. In this setting a functional depression of neurons from the posterior parietal cortex may occur, possibly mediated by chemical factors.
