Pulmonary sequestration is defined as a lung tissue having no communication with the normal tracheobronchial tree and receiving blood supply from a different systemic artery. A paranchymal lesion involving cystic areas was detected in the left lower lobe of the lung in chest x-ray and computed tomography of a 2-year-old boy admitted with the complaints of cough and respiratory distress. The definitive diagnosis of pulmonary sequestration was made by demonstrating the feeding arteries in magnetic resonance angiography performed to identify the etiology of the mass. Magnetic resonance angiography gives detailed information about both vascular structures and associated anomalies of sequestration as a noninvasive procedure in children.
