The case of a boy aged 13 years with Haemophilus influenzae type b meningitis is presented. Six years previously, splenectomy was performed on account of trauma. He died from the meningitis after ten days despite the recommended antibiotic treatment. Splenectomized patients should always seek medical advice at the first of any infection. If there is any doubt about the severity of infection, these patients should be admitted to hospital. Some countries recommended administration of Haemophilus influenzae type b vaccine to patients at risk.
