Silo-Filler's Disease: Nitrogen Dioxide-Induced Lung Injury

Abstract

A patient has been followed for 7 years after exposure to silage gas. His chest film showed diffuse reticular and fine nodular infiltrates. Except for mild hypoventilation and hypoxemia his pulmonary function has remained normal. Persistent lung malfunction after exposure to silage gas is uncommon in those patients who recover from the initial toxic pulmonary edema. Reported cases of chronic lung disability after silage gas inhalation were probably due to other causes, such as chronic bronchitis.
