Intralobar pulmonary sequestration. A 26-year-old woman with recurrent hemoptysis. Contrast-enhanced spiral computed tomography (CT) shows the aberrant artery (arrow) originated from thoracic aorta and introduced to lower left lobe of the lung.

Contrast-enhanced spiral computed tomography (CT) of the thorax revealed an aberrant vascular structure extending from thoracic aorta to lower left lung and 5 mm in diameter [Figures 1 and 2].
Computed tomography image of the lung shows small intralobar sequestrated area as bronchiectasis (arrow) in the left lower lobe (LLL).

Contrast-enhanced spiral computed tomography (CT) of the thorax revealed an aberrant vascular structure extending from thoracic aorta to lower left lung and 5 mm in diameter [Figures 1 and 2].
Aortography image reveals the aberrant arteries (arrow). The anomalous artery originates from the distal part of the thoracic aorta and supplies the blood circulation of the sequestrated lung tissue.

Thoracic aortography confirmed the pulmonary sequestration and aberrant arterial vessel from aorta to LLL and venous drainage from sequestrated area to the left atrium [Figure 3].
Operative view of the patient. Dia: Diaphragm, Ao: Aorta, Ar: Aberrant artery, IPV: Inferior pulmonary vein, LLL: Left lower lobe.

The left posterolateral thoracotomy was performed and the sequestered tissue was found at the baseline of the LLL of the lung [Figure 4].
H and E, x40 magnification of the specimen reveals intra-alveolar hemorrhages (IAH), parenchymal hemorrhages (PH), and vascular congestions (arrow). Al: Alveolus.

Pathological examination of the lung tissue revealed intralobar (ILS) sequestrated lung with focal intra-alveolar hemorrhages (IAH), parenchymal hemorrhages (PH), and vascular congestions [Figure 5].
