Congenital lung malformations (CLMs) are rare developmental anomalies of the lung, including congenital pulmonary airway malformations, bronchopulmonary sequestration (BPS), congenital lobar overinflation, bronchogenic cyst, and isolated congenital bronchial atresia. CLMs occur in 4 out of 10,000 live births. BPS can be intralobar or extralobar sequestration. The condition is often misdiagnosed
therefore, more research on the clinical characteristics of pulmonary sequestration should be carried out to improve the preoperative diagnosis rate. The goal of our case report is to increase awareness of this condition, to diagnose and treat it early, so that it is resected before the development of complications appear. We presented a case of a 32-year-old female patient who presented with a lung abscess and was diagnosed with pulmonary sequestration.
