Final Diagnosis
Intralobar Pulmonary Sequestration
8/15/2005
History of recurrent pneumonia
Surgical Report
• Intralobar Pulmonary Sequestration, treated with right lower lobectomy
• Two major arteries from the thoracic aorta• Large vein draining sequestered lobe
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
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.
