Case report: Pulmonary sequestration in an adult.

Pulmonary sequestration is a rare congenital malformation that is uncommonly diagnosed during adulthood. Pulmonary sequestrations can manifest with variable presentations. It can remain asymptomatic or present with more severe symptoms such as hemoptysis and recurrent pneumonia. Diagnosis can be confirmed with computed tomography angiogram or angiography. Treatment with embolization of the afferent artery and surgical removal of the pulmonary sequestration generally has good outcomes. We report a case of a 43-year-old man who presented with recurrent pneumonia and left-sided back pain and was eventually diagnosed with pulmonary sequestration.
