Pneumocephalus develops due to various reasons; however, pneumocephalus caused by factors other than head trauma is rare, and a few cases of infections have been reported. We encountered a case of pneumocephalus caused by Enterobacter cloacae meningoencephalitis following cerebral infarction. Although we could not perform cerebrospinal fluid analysis and culture, E. cloacae was cultured from blood. We conducted an autopsy and confirmed meningoencephalitis in the cerebral infarction lesion. Thus, we considered that E. cloacae meningoencephalitis caused the pneumocephalus. Because bacterial meningoencephalitis is a treatable disease, we should strictly consider that meningoencephalitis due to bacteria such as E. cloacae causes pneumocephalus.
