Intrapulmonary Sequestration Presenting with Hemoptysis in a Young Adult Female: A Rare Case Report

ntrapulmonary Sequestration with Hemoptysis

Abstract

Pulmonary sequestration is a rare congenital anomaly characterized by nonfunctional lung tissue that lacks communication with the tracheobronchial tree and receives its arterial blood supply from the systemic circulation. Although it is typically diagnosed in childhood, presentation in adulthood is uncommon and may pose diagnostic challenges. We report the case of a 23-year-old female patient who presented to the emergency department with massive hemoptysis of approximately 250 cc per day. Radiological evaluation, including computed tomography angiography, revealed findings consistent with intrapulmonary sequestration supplied by an aberrant systemic artery. The patient was successfully treated with endovascular embolization, resulting in complete resolution of hemoptysis. She was discharged in stable condition with a plan for elective thoracic surgical evaluation. This case highlights the importance of considering pulmonary sequestration in the differential diagnosis of hemoptysis in young adults and demonstrates the role of endovascular embolization as an effective and minimally invasive therapeutic option.
