Nontraumatic pneumocephalus due to nosocomial Enterobacter cloacae infection.

摘要

Nosocomial meningitis is rare, and routine cerebrospinal fluid study is seldom recommended for hospitalized patients with fever and acute delirium. We present a case of Enterobacter cloacae meningitis complicated with a nontraumatic pneumocephalus. Maintaining a high index of suspicion of nosocomial meningitis is crucial in patients with acute delirium and multiple underlying comorbid conditions.
