  • Title: Recognition of an extralobar pulmonary sequestration during lung resection.
    Author: Zhang M, Tang W, Shi H, Tu X, Li W, Wei Z.
    Journal: J Cardiothorac Surg; 2024 Jul 13; 19(1):440. PubMed ID: 39003485.
    Abstract:
    BACKGROUND: Extralobar pulmonary sequestration is located outside the lung parenchyma and is covered by a separated pleural sac, which comprises approximately 25% of all pulmonary sequestration. CASE PRESENTATION: This article reported one case of an extralobar pulmonary sequestration originated from the mesoesophagus, which was recognized and excised during a lung resection. Histologic examination revealed an ectopic lung tissue with hyperplasia of bronchioles, which was accord with an extralobar pulmonary sequestration. CONCLUSIONS: CT angiogram, ultrasound and MRI can be used to clarify the diagnosis and detect the abnormal feeding arteries of extralobar pulmonary sequestration. Carefulness should be taken while dissecting and ligating the potential feeding arteries. Endovascular occlusion might be an alternative option to surgery.
