Intralobar sequestration

Case contributed by Dr Jayanth Keshavamurthy


Pre-operative chest radiograph for cholecystectomy. CT scan of chest undertaken.

Patient Data

Age: 30
Gender: Female

Abnormal lucencies in the right lower lobe, suggesting air trapping.


There are areas of air trapping in the right lower lobe as these areas do not communicate with the more central bronchi. Also there is increased density in the bronchiectatic bronchi, compatible with mucous plugging.


Intraoperative photograph is showing abnormal vascular supply arising from the abdominal aorta to the right lower lobe. 


The histopathologic findings include chronic inflammatory changes including bronchiectasis, dilatation of bronchioles, foci of necrosis, acute and chronic inflammatory infiltrates, and abnormally thick-walled blood vessel(s), also consistent with intralobar sequestration.
