Bronchopulmonary sequestration. Unusual cause of a lung mass in an adult

Bronchopulmonary sequestration is a relatively rare, albeit important, cause of pulmonary disease in the adult. It is characterized by a segment of non-functioning lung parenchyma that receives its blood supply from an anomalous systemic artery. Although chest roentgenography and arteriography are useful in detecting this condition, the most crucial element in diagnosis is a high index of suspicion. Bronchopulmonary sequestration is clinically significant because of its potential for medical and surgical complications. Surgery continues to be the appropriate treatment for symptomatic patients, but experts disagree on the most appropriate management for patients who are asymptomatic.
