Rare presentation of pseudosequestration in childhood: CT and CT angiography findings.

Anomalous systemic arterial supply to the lungs with normal bronchial branching and pulmonary arterial supply is an unusual variant of the sequestration spectrum. Pseudosequestration is referred as the combination of systemic arterial supply to lung with normal bronchial connection. Thorax computed tomography (CT) and CT angiography are non-invasive and useful techniques in making the definitive diagnosis. Herein, we report two paediatric patients with anomalous systemic arterial supply to normal basal segments of the lower lobes.
