Neuromyelitis optica spectrum disorder with radiological manifestation of multiple sclerosis in the first brain MRI: a case report

A small percentage of patients with neuromyelitis optica spectrum disorder (NMOSD) may have radiological manifestations that completely mimic MS. Accurate diagnosis in these patients requires paying attention to patients’ history and how they respond to treatment. Here, a patient with NMOSD is introduced, in the MRI scan of whom, the diagnostic criteria of Barkhof were outlined; however, since her blurred vision did not respond to treatment with corticosteroids, she was diagnosed with NMOSD.
