One month after hospital discharge, the patient consulted again due to functional deterioration associated with fever, jaundice, mutism, asthenia, hyporexia and insomnia; Physical examination revealed nuchal rigidity and positive Brudzinski's sign, with lumbar puncture reporting xanthochromic cerebrospinal fluid, with marked pleocytosis at the expense of neutrophils, hyperproteinorrachia and hypoglycorrhachia with glycorrhachia/glycemia index 0.19 (Table 1) and negative meningitis/encephalitis panel.With the diagnosis of meningitis, broad-spectrum antibiotic treatment was started and the patient was transferred to the intensive care unit.A simple cranial tomography was performed, which showed extensive hypodensity in the region of the left middle cerebral artery with vasogenic edema, confirming by contrasted cerebral resonance imaging that it was a vasculitic process associated with neuroinfection (Figure 1).
