Conservative Management on Antenatally Found Congenital Cystic Adenomatoid Malformation: A 1-Year Follow-Up Case Report.

OBJECTIVE

We report a rare case of congenital cystic adenomatoid malformation (CCAM) diagnosed antenatally based on USG and postnatally based on babygram, CT scan, and chest x-ray. We follow up the baby up to 1 year of age.

METHOD: This study is a retrospective case report describing the clinical presentation, diagnosis, and management of a single patient.

RESULTS

The patient is an outpatient clinic with a diagnosis of G2P1A0, gestational age 38-39 weeks with breech presentation, not in labor, and the fetus is suspected for CCAM. The patient was planned for termination with cesarean delivery. The patient was first diagnosed with CCAM based on antenatal USG examination: A cystic mass in the thorax region of the fetus measuring 1.5 cm was found. The baby was then born by CS in consideration of breech presentation. At birth, the baby had a good APGAR score of 7-8-9. The baby underwent a babygram at 2 days old, which showed a CPAM type III result; CT scan at 16 days old showed infected CPAM type I/CCAM. The baby has been observed for 1 year of life, and no signs of respiratory distress were found. The latest chest x-ray at 1 year of age showed left superior pulmonary cyst.

CONCLUSION

CCAM can be diagnosed perinatally by ultrasound examination. Management of CCAM depends on the size of the lesion and whether significant respiratory distress is present in the newborn. In our case, the CCAM was established prenatally and postnatally; no signs of respiratory symptoms were found within 1 year of age.
