[A case of diffuse aspiration bronchiolitis secondary to achalasia of the esophagus].

A 12-year-old male was admitted to our hospital because of cough, sputum and increasing fever. Chest CT revealed ill-defined small round opacities located around the end of the bronchovascular branchings in almost all of the lung fields. These findings were compatible with diffuse panbronchiolities (DPB). On the other hand, the boy was diagnosed as having achalasia of the esophagus and fragments of food were observed in the bronchi by bronchoscopy. Repeated aspiration and infection due to achalasia are factors which brought about diffuse aspiration bronchiolitis (DAB).
