Multimodality Imaging and Endovascular Management of Intralobar Pulmonary Sequestration in a Young Female: A Case Report

Pulmonary sequestration is an uncommon congenital lung anomaly in which non-functioning lung tissue lacks communication with the tracheobronchial tree and receives blood supply from an abnormal systemic artery. Intralobar sequestration, though less frequent, often presents with recurrent respiratory infections in children and adolescents. This case report describes a young female with a long history of recurrent fever and pneumonia who was evaluated using multimodality imaging. Imaging revealed cavitary lesions in the left lower lung. CT angiography demonstrated an aberrant artery arising from the abdominal aorta, findings consistent with intralobar pulmonary sequestration The patient was initially managed with drainage and antibiotics, followed by endovascular coil embolisation of the anomalous artery. This reduced the risk of bleeding and facilitated a safe, planned surgical removal of the sequestered lung tissue. This case demonstrates the value of combining modern imaging and minimally invasive embolisation with surgery to achieve safe and effective management of pulmonary sequestration.
