[Three cases of adult intrapulmonary sequestration].

Three cases of adult intrapulmonary sequestration were presented. They were all females ranging from 22 to 49-year-old (mean age 35 yrs.). Chest X-rays showed abnormal shadows in the right or left lower lobe. Aortograms showed aberrant arteries in each cases, and the diagnosis of pulmonaly sequestration was made preoperatively. Lobectomies were performed in all cases because of recurrent bronchopulmonary infections. We could not classify our cases based on Pryce's classification by unclear margins between sequestrated lungs and normal pulmonary tissues. All cases had no histories of infantile bronchopulmonary infections which supported the theory of acquired origin.
