INTRODUCTION: Intralobar pulmonary sequestration [ILS] is overall the most common form of Bronchopulmonary sequestration (BPS) usually occurring in the left lower lobe commonly presenting as consolidation in the lower lung lobes. METHODS: A young male [23 years] presented with hemoptysis and a large cavity with air fluid level in the left lower lung lobe for 6-7 years. Computed Tomography of chest and bronchoscopy were inconclusive and therefore he was taken up for lobectomy. RESULTS: The intraoperative finding was a sequestered lower lobe with a separate arterial supply directly from the thoracic aorta CONCLUSION: Cystic and cavitary lesions are rare presentations of ILS and are often diagnosed only during surgery. This is a rare case of pulmonary sequestration that presented to us in the form of a lung abscess.
