title: Pseudosequestration.
abstract: Three children with radiologic findings consistent with right-sided pulmonary sequestration were found at surgery to have a defect in the right hemidiaphragm which permitted a portion of normal liver to herniate into the chest and was associated with an anomalous systemic circulation to the right lower lobe. We refer to this abnormality as "pseudosequestration" and feel it is related to true pulmonary sequestration within the sequestration spectrum.
