Lung window images of CT angiogram of the chest showed heterogeneous consolidation, predominantly in posterior basal segment of the left lower lobe with punctate calcification and tiny focal cavitations measuring approximately 7.7 x 9.0 x 10 cm.
The lesion is supplied by two large systemic arterial branches from the left lateral wall of distal descending thoracic aorta measuring 10-12 mm in diameter. Venous drainage of the lesion was seen into the left inferior pulmonary vein.
Imaging features are consistent with intralobar pulmonary sequestration. CT showed heterogeneous large consolidation in posterior basal segment of left lower lobe, which was supplied by two good caliber systemic arterial branches from distal descending thoracic aorta and subsequent venous drainage into left inferior pulmonary vein. These features are consistent with intralobar pulmonary sequestration.
