One of the diagnostic criteria of neuromyelitis optica (NMO) is a MRI scan at disease onset that does not fulfill the diagnostic criteria for MS. Detection of cortical lesions (CLs) in patients with MS has significantly increased with the use of double inversion recovery sequences. If CLs are a common finding in NMO on the other hand is unknown. First results in a small sample of four NMO patients showed CLs in all patients, suggesting that the absence of CLs is not suggestive for NMO.
