A Case of an Uncommon Cause of Pulmonary Abscess: Intralobar Bronchopulmonary Sequestration

A patient in her early 20s presented with a cough and elevated inflammatory markers. A chest radiograph revealed an abnormal opacity in the right lower zone. Subsequent computed tomography showed an abscess in the right lower lobe that was fed by an anomalous vessel arising from the aorta. These findings were consistent with intralobar sequestration complicated by abscess formation. The patient was treated with antibiotics and discharged home, with plans for elective embolization and lobectomy under the care of the cardiothoracic surgeons. A literature review revealed a limited body of work on pulmonary sequestrations, with very few reported cases involving similar presentations. Thus, our case represents a rare and important addition to the literature.
