  • Title: Intralobar pulmonary sequestration supplied by vessel from the inferior vena cava: Literature overview and case report.
    Author: Cong CV, Ly TT, Duc NM.
    Journal: Radiol Case Rep; 2022 Apr; 17(4):1345-1353. PubMed ID: 35242263.
    Abstract:
    Sequestration is a congenital abnormality that can occur in both children and adults. The clinical presentation often manifests as recurrent pneumonia throughout the lifetime of the patient. Pathologically, sequestration is a disorganized region of lung parenchyma without a normal pulmonary artery and with no interconnecting air passage (ie, it is isolated from the bronchi and pulmonary arteries). Sequestration can be either intralobar or extralobar and is usually supplied with blood from an anomalous vessel originating from the thoracic aorta or abdominal aorta (big circulation/systemic circulation), which is one of the mandatory criteria for diagnosing sequestration. CT angiography or catheter angiography can assist in identifying the anomalous vessel both for diagnosis and surgical resection. We present a rare case of intralobar sequestration with the distinction of being supplied with blood from the abdominal vena cava, as confirmed by CT angiography, surgery, and postoperative pathology. It is hoped that this study will contribute to the literature by introducing a rare case of congenital lung abnormality and pulmonary vascular malformation.
