A young woman was examined in the Emergency Department for fever, pharyngitis and widespread petechial rash. Physical examination, including neurological evaluation, did not show any other abnormalities. Chest X-ray was negative. Blood exams showed leukocytosis and CPR 20 mg/dL (nv<0.5 mg/dL). On the basis of these results and petechial rash evidence, lumbar puncture was performed. CSF was opalescent; physico-chemical examination showed: total proteins 2.8 (nv 0.15-0.45), glucose 5 (nv 59-80), WBC 7600/μL (nv 0-4/ μL). In the hypothesis of meningococcal meningitis, antimicrobial therapy was started. Blood and cerebrospinal fluid cultures were positive for N. meningitidis. During the first hours the patient experienced hallucinations and mild psychomotor agitation, making a spontaneous recovery. A brain MRI showed minimal extra-axial inflammatory exudates. She was discharged after 10 days in good condition. We underline the need to consider meningococcal meningitis diagnosis when any suggestive symptom or sign is present, even in the absence of the classic meningitis triad, to obtain earlier diagnosis and an improved prognosis.
