Abstract:
Objective To explore the clinical value and typing characteristic of prenatal ultrasonography for fetal cystic adenomatoid malformation of the lung(CAML).Methods Ultrasonographic features and typing of fetal CAML in 41 cases detected by prenatal ultrasonography were analyzed retrospectively.All cases were followed up until to the induction of labor or birth.Results (1)Site of tumor: in the 41 cases,there were 22 cases on the left side,15 on the right side and 4 on bilateral.(2)Typing diagnosis of prenatal ultrasonography: three cases were CAML type Ⅰ,14 were type Ⅱ,and 24 cases were type Ⅲ.(3)Pathology diagnosis: thirty two cases were induced abortion.CAML was confirmed in 29 cases by autopsy and the classifications were consistent with the prenatal diagnosis of ultrasonography.Three pulmonary sequestration cases were prenatally misdiagnosed as CAML type Ⅲ by ultrasonography.(4)The other nine cases were followed up to birth.Three masses decreased gradually and then disappeared.Six newborns were confirmed as CAML by CT.Their typings were consistent with the postnatal diagnosis.(5)The diagnostic accuracy rate of prenatal ultrasonography for CAML was 92.7%(38/41).Its misdiagnostic rate was 7.3%(3/41).Conclusions Prenatal ultrasonography has a high accuracy rate for the diagnosis and classification of CAML and is the first choice to detect CAML early in pregnancy.It has an important clinical value.Pulmonary sequestration should be distinguished from CAML type Ⅲ because they tend to be confused.
