Intralobar sequestration involving the left lower lobe with systemic arterial supply of the sequestered segment from the descending thoracic aorta.
This case is interesting as the patient presented with hemoptysis (unusual as the sequestered segment should not technically communicate with bronchial tree). There have been case reports of hemoptysis as the main presenting complaint 1. The small region of ground-glass lung parenchymal attenuation may represent hemorrhage in this setting.
This patient underwent surgical excision as is the mainstay of treatment.
