RESUMO
We report 30 patients with exogenous lipoid pneumonia due to vegetal oil. This was employed in most of the cases during the first month of life for digestive tube symptomatology; clinical manifestations began three months following administrations, as a pneumonia or bronchopneumonia with a respiratory distress syndrome of variable severity. 60% of the thorax x-ray studies were abnormal, the main finding was opacity. One patient has alterations of the mechanics of deglutition; seven had gastroesophageal reflux. Arterial gasometry showed hypoxaemia and increase of alveolo-arterial gradient of oxygen in all. Ten patients died and all the survivors were reevaluated in september, 1988; 18 had normal physical findings. Thorax x-ray studies in 13 patients had right reticulate infiltration and 6 right apical opacity; ECG showed right ventricular hypertrophy in 3. Perfusion pulmonary gamagram with technetium 99 was abnormal in 5. Gastroesophageal reflux was evident in 2. Five were under treatment for several causes. Diagnosis and treatment is discussed.
