Pulmonary sequestration (intralobar)

Case contributed by Dr Andrew Dixon

Presentation

20 month old boy with persisting abnormality on CXR.

Patient Data

Age: 20 months
Gender: Male
Modality: X-ray

An ill-defined opacity in the right lower zone, adjacent to the right cardiac border, without silhouetting it, suggesting to be located in the left lower lobe. 

Modality: CT
CT with intravenous contrast shows complete collapse of the superior segment of the right lower lobe. A prominent artery arises from thoracic aorta at the level of T7 supplying this segment and it is drained by a large vein into the right pulmonary vein.

Case Discussion

Findings are consistent with intralobar pulmonary sequestration. Right lower lobe sequestration is far less common than left lower lobe sequestration.
