Prenatal diagnosis of right congenital diaphragmatic hernia or Morgagni's hernia

Congenital diaphragmatic hernia appears as a consequence of an abnormal development of the diaphragm muscle, in the stage of embryogenesis. Right diaphragmatic hernia is one of the rarest clinical variants and with a difficult prenatal diagnosis, associated with a high neonatal morbidity and mortality due to complications derived from the anatomo-functional disturbances of the herniated and displaced structures. This type of hernia is associated with genetic anomalies and malformations of other systems. This study presents the case of a pregnant adolescent whose second-trimester fetal ultrasonography, performed in her health district, detected a cardiac area displaced to the left with the impossibility to have a four-chamber visualization. At the provincial reference center of fetal ultrasonography, a diagnosis of right diaphragmatic hernia was made, confirmed by anatomopathological study, which is concluded as a Morgagni's hernia. Due to its clinical importance for the training of health professionals related to the mother and child care, the scientific presentation of the case is proposed.
