Hybrid Lesion: Extralobar Sequestration with Cystic Adenomatoid Malformation - Misdiagnosed as Pulmonary Tuberculosis

We report a rare case of bronchopulmonary extralobar sequestration in a 9-year girl mimicking pulmonary tuberculosis. Patient had recurrent chest infections and two episodes of massive hemoptysis. Preoperative x-ray chest showed an opacity in left lower lobe and computed tomography-aortogram showed that the lesion had systemic arterial supply from celiac trunk. Diagnosis of pulmonary sequestration was made and left lateral muscle sparing thoracotomy was planned. Intraoperatively, extralobar sequestration was found with dual systemic blood supply. Histopathology confirmed it to be a hybrid lesion.
