Extended-spectrum beta-lactamase (ESBL) producing organisms cause wide spectrum of diseases including urinary tract infection, cholangitis, intra-abdominal abscess or pneumonia but rarely meningitis. The present report a successful nonsurgical, medical treatment in a child with Escherichia coli ESBL meningitis with acute
