{Reference Type}: Case Reports {Title}: Pneumocephalus With Stroke-Like Symptoms: A Rare Complication of Mastoiditis. {Author}: Oomrigar SC;Patel RK;Mas RP;Fernandez JC;Zapata DI; {Journal}: Cureus {Volume}: 15 {Issue}: 6 {Year}: 2023 Jun 暂无{DOI}: 10.7759/cureus.40307 {Abstract}: Pneumocephalus is defined as the presence of gas or air in the intracranial space and typically arises as a result of neurotrauma. Clinically, pneumocephalus most often presents asymptomatically but may cause headache, nausea, vomiting, and confusion. Pneumocephalus arising from mastoiditis is an unforeseen complication with only a handful of cases reported. We report a case of an elderly male who presented with stroke-like symptoms in the setting of erosive mastoiditis with pneumocephalus.
