Agenesis of the right lung in an adult woman: A case report.

Key Clinical Message: Pulmonary agenesis is a rare congenital abnormality. Patients with hemithorax white-out on x-rays should be treated with caution, especially in resource-limited countries where chest CT and bronchofibroscopy are not available to confirm the diagnosis.

Abstract: Pulmonary agenesis is an uncommon congenital abnormality defined by the complete absence of the lung parenchyma, as well as the bronchial and vascular structures. Right-sided pulmonary agenesis is less frequent, has a worse prognosis, and is usually associated with other congenital abnormalities. We reported the clinical case of a 31-year-old woman with right pulmonary agenesis, and no other congenital abnormalities, whose diagnosis was confirmed by thoracic computed tomography and bronchofibroscopy and who has a good prognosis.
