Pulmonary sequestration - intralobar

Case contributed by Dr Mostafa El-Feky


Incidental finding at abdominal CT done for follow up after surgical excision of abdominal wall lesion.

Patient Data

Age: 35 years
Gender: Female

CT abdomen with contrast


A consolidative lesion is seen at the medial aspect of the left lower lung lobe, showing arterial supply from the aorta and drain into the pulmonary veins, surrounded by small tree-in-bud nodules and atelectatic bands.

Case Discussion

The above-described features are suggestive of infected intralobar pulmonary sequestration

Pulmonary sequestration commonly affects the lower lobes; 60% of intralobar sequestrations affect the left lower lobe, and 40% the right lower lobe with arterial supply from a branch of the aorta. Intralobar sequestration showed no separable pleural lining from the lung and venous drainage via pulmonary veins.
