A rare case of congenital lobar emphysema presenting as recurrent pneumonia in early adulthood: A case report and literature review

Introduction and significance: Congenital lobar emphysema (CLE) is a rare but important lung malformation typically discovered in the newborn period. Some rare cases are reported in adults. It can present with various respiratory symptoms. Diagnosis relies primarily on chest CT scans, and the main treatment is surgery. Case presentation: We present a case of a young girl with recurrent respiratory infections who was misdiagnosed with a pneumothorax. A chest tube was inserted. Later, CLE was identified, and the affected lung lobe was surgically removed. Clinical discussion: This case highlights the importance of including CLE in the differential diagnosis for hyperinflation of a lung lobe. A CT scan is crucial for confirmation. Conclusion: Congenital lobar emphysema is a rare disease that primarily affects children. Most children with CLE experience symptoms and require surgery. In adults, CLE is uncommon, and surgery is based on the severity of symptoms and radiological findings.
