ABSTRACT

An 85-year-old man was diagnosed with idiopathic pleuroparenchymal fibroelastosis (iPPFE) on chest computed tomography (CT) imaging and was subsequently followed up. Over time, he experienced progressively worsening dyspnea on exertion. A follow-up chest CT scan taken in July of year 20XX revealed left extrapleural air with mediastinal emphysema. A review of existing literature revealed few reported cases of extrapleural air. Herein, we report a case of extrapleural air associated with iPPFE.
