A 24-year-old man was admitted in the emergency department with sudden bilateral visual loss, headache, and fever. Clinical examination showed manifest stiff neck with positive Kernig and Brudzinski signs, a skin rash was also observed on the legs. Cerebrospinal fluid (CSF) examination and brain magnetic resonance imaging (MRI) demonstrated a diagnosis of meningococcal meningitis with infectious optic neuritis aspect.
