Pulmonary sequestration is a rare bronchopulmonary foregut anomaly that occurs when a portion of the lung derives its blood supply from an aberrant vessel rather than the customary tracheobronchial supply. The sequestration can be classified as intralobar or extralobar. Most patients with intralobar sequestration are asymptomatic. Among symptomatic patients, presentations vary greatly, from fever, cough with expectoration, exertional dyspnea, pleuritic chest pain, and hemoptysis to eventual lung abscess or empyema. Contrast-enhanced computed tomography/computed tomography angiography is performed to determine the origin of the anomalous blood supply as well as the pathological manifestations involving the lobes. We present a patient with diagnosed intralobar sequestration who developed pulmonary tuberculosis of the sequestered lung tissue. The patient was successfully managed with long-term antitubercular therapy and left lower lobectomy with ligation of the anomalous vessel.
