A 55-year-old woman was referred to our department complained of hemosputum, and abnormal shadow in the left lower lobe of the lung was noted by chest X-ray film and CT scan. Since no definite diagnosis could be made by the routine examinations, exploratory thoracotomy was performed. At thoracotomy an anomalous artery which originated from the descending aorta and supplied the left basal segment of the lung was detected. Based on the diagnosis as anomalous systemic arterial supply to the basal lung, left lower lobectomy was performed. Postoperative examinations of the resected specimen revealed that S8 and S9 were supplied by the anomalous artery, while, S6 and S10 were supplied by normal pulmonary artery without any sequestrated lung. Clinical features of this disease entity were discussed with a review of the literature.
