In a 20-year-old male patient, a 180 degree inversion of visual image was found as a manifestation of multiple sclerosis. Upside down reversal of vision is not a well-known sign in multiple sclerosis. Exact mechanism is still unknown. Lesions involving cortical areas, mainly the parieto-occipital region, have occasionally been documented. To our knowledge this is the first report of upside-down reversal of vision in multiple sclerosis with cerebra lesion on MRI. Multiple Sclerosis 2008; 14: 266—267. http://msj.sagepub.com
