Pulmonary Sequestration Associated with Actinomycosis: A Case Report.

Bronchopulmonary sequestration is a rare congenital malformation of the lower respiratory tract; it consists of a nonfunctioning mass of lung tissue that is irrigated by an anomalous systemic artery. The association with superinfection has not been well established. We present the case of a 35-year-old woman with a history of recurrent episodes of pneumonia. Based on radiological and histopathological examination, she was diagnosed with intralobar bronchopulmonary sequestration associated with infection. Promoting clinical suspicion is essential to diagnose pulmonary actinomycosis in patients with recurrent pneumonia, to improve early recognition and timely management.
