Uncommon Etiology of Chest Pain: Pulmonary Sequestration

Chest pain is a common presenting symptom in the emergency department. After ruling out emergent causes, emergency physicians need to identify and manage less commonly encountered conditions. Pulmonary sequestration (PS) is a rare congenital condition involving pulmonary parenchyma. In PS, a portion of non-functional lung tissue receives systemic blood supply from an anomalous artery. While most individuals with PS present in early life with symptoms of difficulty feeding, cyanosis, and dyspnea, some present later with recurrent pneumonia, hemoptysis, or productive cough. In this report, we present a case of PS in an adult with acute onset pleuritic chest pain.
