Intrapulmonary bronchogenic cyst mimicking primary lung cancer with atypical radiological findings

Abstract

Introduction: bronchogenic cyst is a congenital disease secondary to abnormal budding of the bronchial tree during embryonic development. It usually develops in the mediastinum and is rarely seen in the lung parenchyma. A diagnosis is often made before surgery because of its typical cystic appearance in computed tomography scan and magnetic resonance imaging scan. case report: A 71-year-old female presented with an abnormal shadow in her right lung on a chest radiograph. she underwent right upper lobectomy, under the suspicion that the nodule was primary lung cancer. Pathological examination showed an intrapulmonary bronchogenic cyst with a thickened cyst wall containing hyalinized fibrous tissue and lymphocyte infiltration. conclusion: Even an asymptomatic bronchogenic cyst might have been affected by an infectious event in the past, and could reveal a variety of atypical radiological findings.
