[Ultrasonics in the study of periencephalic post-traumatic effusions in the newborn and suckling infants].

The authors report their experience in 8 cases of cranial post-traumatic superficial collections, studied by US. Traumatic cranial injuries with superficial collections are not rare in newborns; their early and complete diagnosis is necessary for a correct therapeutic approach. Sonography could be used as a first choice procedure but presents some limitations in the study of the posterior fossa. Therefore CT remains the technique of choice.
