CASE REPORTextended-spectrum β-lactamase (ESBL) E. coli causing the same has not been described previously. Hereby, we describe a successfully treated case of community-acquired meningitis due to E. coli complicated by primary ventriculitis.
Case DesCriptionA 67-year-old elderly female patient with a background of diabetes mellitus and hypothyroidism, suffering from fever and headache for the past 5 days, presented to the emergency department with a history suggestive of generalized tonic-clonic seizures. She was drowsy, agitated, and moving all four limbs with the Glasgow Coma Scale (GCS) of E2V2M4 in a postictal state. The patient was mechanically ventilated in view of poor GCS. Blood sugar was introDuCtion Bacterial meningitis is a medical and neurological emergency requiring early recognition of symptoms, rapid diagnostic evaluation, and appropriate antimicrobial therapy. Common etiology of meningitis in immunocompetent adults are Streptococcus pneumoniae and Neisseria meningitidis attributing to 80% of the cases, followed by Haemophilus influenzae, Streptococcus agalactiae, and Listeria monocytogenes. In adults, gram-negative bacterial (GNB) meningitis is a relatively uncommon etiology of community-acquired meningitis. Gram-negative meningitis occurs after neurosurgical procedures in up to 50% of the cases. Neurosurgical intervention and device implantation, traumatic brain injury within the past 1 month, and cerebrospinal fluid (CSF) leak represent the main portals of entry in up to 75% of the nosocomial cases. 1 Spontaneous community-acquired GNB meningitis represents 8.7% of all spontaneous communityacquired meningitis, with an annual incidence of two cases per 100,000 adults. Escherichia coli (E. coli) represents 41.9% of these cases. E. coli, a rare cause of community-acquired adult meningitis, is a common pathogen among neonates. Community-acquired GNB meningitis occurs almost exclusively in cases with preexisting risk factors, typically secondary to a distant or contiguous foci, such as urinary tract infection, retropharyngeal space infection, otitis media, gastrointestinal focus, etc. 2,3 Mortality of such E. coli meningitis are much higher than other patients with bacterial meningitis. 3,4 Ventriculitis is an uncommon infection affecting the ependymal lining of the ventricles of the brain, also called pyocephalus or ependymitis, or intraventricular empyema. Commonly ventriculitis develops secondary to neurosurgical procedures, Intraventricular devices, or ruptured complicated brain abscesses. Primary ventriculitis is a very rare phenomenon, and
