RESUMO
Pneumocephalus, or air entrapment within the cranium, is a rare but dangerous condition with a variety of causes, including trauma, surgery, or predisposing infection. Trauma is the most common etiology, as fractures provide easy access for air to become entrapped in the cranium. However, access such as via the central nervous system with leak exists. Though not as common as traumatic pneumocephalus, pneumocephalus secondary to infection is a dangerous condition. The literature is sparse on this example of ear-nose-throat infection, making it difficult to form and ascertain guidelines for the management of infectious pneumocephalus and its complications. A 58-year-old man with a history of hypertension, obesity, type 2 diabetes mellitus, and obstructive sleep apnea who presented with a complicated case of acute otitis media associated with subdural empyema, pneumocephalus, and group A Streptococcus is presented in this case report. We describe the course of his hospital stay, management, and current infectious disease guidelines. Given the paucity of cases of infectious pneumocephalus secondary to otitis media, we aim to provide further representation for this important illness as well as encourage the use of a multimodal team of providers. In our case, it was necessary to involve the ear-nose-throat specialist as well as infectious disease and neurocritical care services.
