Abstract:
We describe a case of horseshoe lung in an infant with facio-auriculo-vertebral (FAV) sequence that included mild hemifacial microsomia, ear anomalies, a missing left rib, left hemivertebrae (T2-T4), and complex congenital heart disease. Of the approximately 40 cases of horseshoe lung described since 1962, most are reported in association with scimitar syndrome, and only four reported cases were associated with left lung hypoplasia. None of these cases included malformations consistent with a diagnosis of FAV sequence.
