Cerebrovascular phenomena have been well documented in traditional reviews of bacterial meningitis in children and adults alike.1Weisfelt M. de Gans J. van der Poll T. van de Beek D.

A previously healthy 5-year-old boy presented with a 36-h history of muscle tenderness, fever, and headache. In the preceding 3 h, the patient had developed petechiae on his skin and mucosal surfaces. Upon examination, he presented neck stiffness, and his Glasgow Coma Scale score was 14. His vital signs were as follows: axillary temperature 37.5 °C, pulse 150 bpm, respiration 30 breaths/min, and blood pressure 100/60 mmHg. The preliminary diagnosis was meningococcal meningitis with sepsis. Therefore, we initiated antibiotic treatment with intravenous ceftriaxone (100 mg/kg/day for seven days) and dexamethasone (0.6 mg/kg/day for four days). His white blood cell (WBC) count was 18.5 × 109/l and platelet count was 52 × 109 cells/l. Coagulation studies demonstrated an international normalized ratio (INR) of 2.0 and an activated partial thromboplastin time of 60 s. A computed tomography (CT) scan of the brain was normal, and a lumbar puncture was performed after transfusion of fresh-frozen plasma and platelets. The cerebrospinal fluid (CSF) contained 940 × 106 WBC/l and 269 mg/dl of protein, and the CSF glucose/blood glucose ratio was 0.10. Gram stain of the CSF showed Gram-negative diplococci. The results of the latex agglutination test and counterimmunoelectrophoresis of the CSF were positive for N. meningitidis serogroup B, as were those of the CSF culture. The patient demonstrated clinical and hemostatic improvement during the first 24 h. However, on the second day of hospitalization, his level of consciousness deteriorated rapidly. A second CT scan of the brain revealed a high-density area in the right cerebellar hemisphere, suggesting cerebellar hemorrhage (Figure 1). The platelet count was 82 × 109 cells/l and coagulation studies demonstrated an INR of 1.6. Transesophageal echocardiogram and extracranial carotid Doppler study results were within normal limits. One week after the hemorrhagic phenomenon, a neurological examination showed a nearly complete clinical recovery and a CT scan revealed virtually total absorption of the hematoma (Figure 2). In a routine follow-up examination, performed 9 months later, the patient reported no further problems.Figure 2Brain CT image on the seventh day of hospitalization, showing a virtually total absorption of the hematoma.View Large Image Figure ViewerDownload Hi-res image Download (PPT) Cerebrovascular accidents are determinants of unfavorable outcomes in bacterial meningitis, and they manifest clinically as focal neurological deficits or as a decrease in consciousness.2van de Beek D. de Gans J.

Therefore, it is probable that, in meningococcal infection, strokes are related to both local (endothelial damage) as well as systemic (imbalance of hemostatic forces) mechanisms.
