BACKGROUND A 45-year-old serving soldier, treated as a case of pulmonary tuberculosis in 2003 for a right paracardiac mass, was found to have persisting opacity in the same region during periodic medical examination. He was extensively evaluated and diagnosed as a case of benign mass lesion in right lower lobe. Patient recently reported for review and underwent contrast-enhanced computed tomography (CECT ) chest for present status of mass lesion. He was asymptomatic.

ANSWER

Intralobar sequestration of lung right lower lobe. (Black arrow showing arterial supply to sequestrated lung from aorta and white arrow showing thoracic aorta.)
1.

Sequestration of lung is a rare congenital anomaly which occurs due to aberration in bronchial tree with associated abnormal arterial blood supply. Intralobar is more common than extralobar which are differentiated by presence of separate pleural membrane in extralobar. The commonest involvement is left sided, involving basal segments with arterial supply from thoracic aorta (as seen in CECT chest). Treatment is surgical removal of sequestrated lung with carefully identifying the feeding vessel and maintaining hemostatsis.[1-4]
