[Haemorrhages of the posterior fossa in full-term newborns (author's transl)].

Four cases of non-traumatic haemorrhage of the posterior fossa in full-term newborns are reported and compared with the 30 cases already published. Computerized tomography is the only method that permits both a diagnostic and a therapeutic approach. Surgery is indicated in the presence of brain stem compression but should be carefully discussed in cases of intracerebellar haemorrhage with secondary extension to the posterior fossa. Early hydrocephalus is common and requires shunting in about 25% of the cases
