A case of systemic arterialization of lung without sequestration

Intralobar pulmonary sequestration is a congenital disease characterized by nonfunctioning lung tissue with an anomalous blood supply stemming from the systemic circulation. We report a rare case of anomalous systemic arterial supply to the lung without demonstrable pulmonary changes. It is controversial whether this abnormality, systemic arterialization of lung without sequestration, should be a subtype of sequestration complex or not. We discuss the spectrum of sequestration complex.
