Prenatal diagnosis of congenital cystic adenomatoid malformation using three-dimensional inversion rendering: A case report

subject

description

We report a case of a congenital cystic adenomatoid malformation of the lung (CCAM). At 12 weeks of gestation, an echogenic lung associated to a hydrothorax was detected. Despite the results of the combined test that informed of a high risk of chromosomopathy, normal karyotype was confirmed after an amniocentesis. The three-dimensional ultrasound inversion mode depicted all the cysts within the fetal lungs as opaque areas that were seen concurrently together, which was compatible with CCAM. After parental counseling, the patient opted to terminate the pregnancy at 18 weeks. Pathological analysis of the lungs confirmed the diagnosis of a CCAM type II. The recent advent of the three-dimensional ultrasound inversion mode opens many diagnostic options until now unavailable or difficult to attain sonographically and therefore it may help us to increase the sonographic detection rates of congenital cystic adenomatoid malformation.
