Extralobar Pulmonary Sequestration in a Fetus: Ultrasound, Doppler, CTA, Diagnosis and Treatment
How prenatal Doppler identifies the systemic feeding artery and how postnatal CTA defines the vascular anatomy of fetal extralobar pulmonary sequestration. MediAI by ScholarGen Where Medical Imaging & AI Meets Humanity Executive Clinical Summary A fetal thoracic mass discovered during routine prenatal ultrasonography can immediately raise concern for congenital pulmonary airway malformation, diaphragmatic hernia, bronchogenic cyst, or other developmental abnormalities. Yet one imaging feature can fundamentally change the diagnostic pathway: a systemic feeding artery arising from the aorta . This vascular finding is particularly important in extralobar pulmonary sequestration (ELS) , a congenital malformation consisting of nonfunctioning pulmonary tissue that has no normal bronchial communication and is separated from the normally developing lung by its own pleural covering. The present case illustrates the classic diagnostic sequence. At 21 weeks of gestation , fetal ultrasoun...
