[Posthemorrhage porencephalic cysts in the neonatal period. Diagnosis. Etiology. Development. Value of transfontanellar echography].
Cerebral echotomography interest in showing neonatal cerebral hemorrhage and their follow up toward porencephaly is pointed out in 4 neonates. The authors recall the electroencephalographic features which can lead to the diagnosis. Then, they insist upon a new concept which is the long delay between onset of the cyst and onset of hemiplegia. The rationnal for this concept is the gradual maturation of the pyramidal tracts in infancy.
