Four patients with abnormal chest roentgenograms were evaluated and were proven intralobar pulmonary sequestration (IPS) at surgery. A 7-year-old boy and a 26-year old man had left lower IPS. Helical 3D-CT demonstrated the aberrant artery arising from the descending thoracic aorta and the draining pulmonary veins. They underwent left lower lobectomy. A 23-year-old man and a 35-year-old woman had right lower IPS. Helical 3D-CT demonstrated the aberrant artery arising from the abdominal aorta and the draining pulmonary veins. They were treated by left lower partial lobectomy. Helical 3D-CT is noninvasive, and provides accurate, three-dimensional information of the aberrant vascular supply of the pulmonary sequestration, which closely simulates the angiographic and surgical findings. Helical 3D-CT can replace angiography in the preoperative diagnosis of the pulmonary sequestration.
