Intralobar Pulmonary Sequestration with Aspergilloma and a Large Aberrant Artery in a 35 Year Old Man

A 35 year old man presented with a 4 month history of cough, hemoptysis, malaise, and fever (>38°C) and moderate (6 kg) weight loss. Investigations with CT scan of the chest revealed a cavitary lesion in the lower lobe of the left lung suggesting the presence of a pulmonary aspergilloma, the remaining lung fields being clear. There was no history of any pulmonary infections. Surgical excision of the affected lobe was performed. During surgical exploration we found that the affected lobe receives its blood supply by a large artery from the thoracic aorta. During follow-up his clinical status is excellent.
