[Ultrasound in the diagnosis of congenital malformations of the brain].

After the work published by Kossof (1974), on the use of ultrasound for the study of trans-sectional cuts in the brain of newborns, the technic has been widely used in the exploration of this organ. This study evaluates the use of ultrasound in the diagnosis of congenital malformations of the brain in 11 patients seen during a period of 3 years at a regional hospital of southern Chile. The classification introduced by Beberly and Zimmerman was used in order to ascribe each case to a correspondent phase of organogenesis. Recent studies over the advantages of ultrasound for the detection of congenital malformations of the brain have resulted in the replacement of traditional invasive methods by ultrasonography for the evaluation of these problems.
