[Three cases of intralobar pulmonary sequestration--demonstration of an aberrant artery by contrast CT]

Three cases of intralobar pulmonary sequestration, whose aberrant arteries could be demonstrated by contrast CT were reported. We confirmed these aberrant arteries both by selective angiography and/or surgical resection. We conclude that contrast CT may be of great use and benefit in the radiological workup of suspected cases of pulmonary sequestration proceeding to angiography.
