Giant branching aneurysmal aberrant systemic artery for intralobar pulmonary sequestration: computed tomographic depiction of arterial and bronchial anomaly

Abstract

Aberrant systemic arteries supplying the intralobar pulmonary sequestration can become dilated and have atherosclerotic change. Computed tomography is very useful in demonstrating the aberrant artery. We report a case of intralobar pulmonary sequestration with giant branching aneurysmal aberrant artery, and demonstrated the discontinuity of the bronchus by 64-slice computed tomography, which has not previously been described.
