Dual arterial supply to normal lung: within the sequestration spectrum.
We report a rare case of dual arterial supply to an otherwise normal left lower lobe. In addition to normal pulmonary arterial supply, the lower lobe of the left lung also received systemic arterial supply from the coeliac axis. The relevant anatomy and literature are reviewed. To the best of our knowledge, there are no other reported cases of anomalous systemic arterial supply from the coeliac axis to the basal segments of the left lower lobe with normal bronchial branching and pulmonary arterial supply.
