[Prenatal diagnosis of type II adenomatoid lung dysplasia].

Congenital adenomatoid malformation of the lung is a rare form of lung disease, characterised by excessive overgrowth of terminal respiratory elements. From the histological as well as the sonographical point of view it can be classified into 3 subtypes. The prognosis depends on the type and the associated malformations. We report on two cases of congenital adenomatoid malformation of the lung type II, diagnosed by ultrasound before the 23rd week of gestation. Criteria that may be useful in the prenatal diagnosis of this malformation are described, and the clinical management is discussed.
