Introduction: Fetal echogenic lung lesions (ELL) are the commonest pulmonary pathology diagnosed on antenatal sonography, and include congenital pulmonary airway malformations (CPAMs) and bronchopulmonary sequestrations. This study aimed to evaluate the predictive utility of the CPAM volume ratio (CVR) at presentation in a series of fetuses with ELLs at a tertiary Australian referral hospital. Material and methods: Retrospective cohort study of all pregnancies with a prenatal diagnosis of an isolated fetal echogenic lung lesion managed at the Royal Women’s Hospital, Victoria, Australia, between 2005 and 2015. Data were obtained from electronic ultrasound image databases and medical records. Results: Sixty-five cases were included in the final analysis. The mean gestation at presentation was 22 weeks and 6 d, and the mean CVR was 0.66. Hydrops was evident in four cases at presentation, and did not develop subsequently in any other case. Significant perinatal concerns–fetal/neonatal demise, hydrops, requirement for neonatal intubation/ventilation, or surgery in the first year of life–did not occur with or following a CVR at presentation of <0.45. The survival rate at 1 year was 95%. Discussion: The CVR is a potentially useful tool to assess all fetal ELLs, and not just those presumed to be CPAMs. A CVR at presentation of <0.45 was associated with favourable outcomes.
