PY - 2015 T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsPulmonary agenesis is defined as complete absence or severe hypoplasia of one or both lungs.Pulmonary agenesis may be found in isolation or in association with other malformations.Bilateral agenesis of the lung is rare, and is incompatible with life; unilateral agenesis occurs more commonly, and may be compatible with normal life.Sonographically, the mediastinum is shifted toward the affected side and the diaphragm on the ipsilateral side is elevated.Detailed sonography and fetal magnetic resonance imaging (MRI) may distinguish unilateral pulmonary agenesis from other causes of mediastinal shift.Unilateral or bilateral pulmonary agenesis is not thought to be associated with chromosomal abnormalities.
