Bronchopulmonary Sequestration
Definition• Non-functioning lung tissue • Separated from normal bronchial tree• Vascularized by a systemic artery
Two Forms• Intralobar (ILS): within the visceral pleura• Extralobar (ELS): separated from the lung by its
own pleura
![Page 14: Final Diagnosis](https://reader036.vdocuments.us/reader036/viewer/2022062810/56815bbd550346895dc9bb69/html5/thumbnails/14.jpg)
Intralobar Pulmonary Sequestration (ILS)
Characteristics• More common type• May present at any age• Generally as recurrent infection• No sexual predominance• Almost exclusively affects lower lobe• Arterial supply: descending aorta• Venous drainage: pulmonary veins

Etiology of Bronchopulmonary
Sequestration
• Accessory bud that forms caudal to lung buds• Traction theory• Postnatal formation

Pulmonary SequestrationComplications
• Recurrent infection• Heart failure• Intralobar malignancy

Treatment of Pulmonary Sequestration
Symptomatic Disease• Surgery: lobectomy or segmental resection• Arterial embolization

Patient Follow-up
• Given granulomas and acid fast bacilli, sputum was sent for culture. Three sputum samples were negative for acid fast bacilli. A ppd was placed and was also negative.
• Patient was treated empirically with IRPE for four months.
