title: [Predictive value of prenatal MRI in the diagnosis of thoracic congenital malformations].
abstract: BACKGROUND
  Magnetic imaging (MI) has an increasing value in the prenatal diagnosis of thoracic malformations. MATERIAL AND METHOUS: We compare in this work the prenatal diagnoses with the prenatal sonographic diagnoses and postnatal imaging, surgical or postmortem findings.
  
  
  RESULTS
  Prenatal sonography diagnosed 5 diaphragmatic hernias (CDH) and 3 cystic adenomatoid malformations (CAM). MI confirmed left side CDH in 4 cases, in two of them showing also herniation of the left hepatic lobe and the spleen. In the 5th case, MI suggested diaphragmatic eventration with partial occupation of the right hemithorax by the liver. Two of three CAM appeared to have lung sequestration at MI. At birth, four CDH and one diaphragmatic eventration were confirmed by simple x-ray, and by surgery in all but one, a CDH case who went into ECMO and died without surgery. Pulmonary sequestration was postnatally confirmed by CT scan and arteriography. Treatment was coil embolization of the systemic artery. CAM was confirmed postnatally through plain chest film and CT scan. Surgical resection of the lesion was performed and the pathology exam demonstrated the presumed lesion.
  
  
  CONCLUSIONS
  When prenatal sonography suggest a fetal thoracic malformation, MI is the way to accurate diagnosis, follow-up, prognostic evaluation and therapeutic strategy.
