Ultrasound and computed tomographic findings of pulmonary sequestration

ABSTRACT

The pulmonary sequestration is rare congenital anomaly characterized by the presence of a part of lung tissuewhich is supplied by an aberrant systemic artery from the aorta or its branch and usually has no communicationwith the normal bronchial tree. The authors present 3 cases of intralobar pulmonary sequestration, studied by CTand /or US. Typical CT features of intralobar pulmonary sequestration are homogenous or unhomogeneous, relativelylow density lung mass near the diaphragm, having feeding artery from the aorta or branching vessels within themass during bolus injection or dynamic CT.
