Abstract:
A 59-year-old man presented with esophageal achalasia complicated by lipoid pneumonia. Dysphagia and diffuse ground-glass shadows on computed tomography led to the diagnosis of esophageal achalasia. An analysis of bronchoalveolar lavage (BAL) revealed yellow BAL fluid, with two distinct layers. Oil droplets were observed in the upper layer. Macrophages that phagocytosed lipids were also observed. He was diagnosed with lipoid pneumonia secondary to esophageal achalasia. His lipoid pneumonia improved after peroral endoscopic myotomy because of the reduction in aspiration risk.
