Hemorrhage in the cavum septi pellucidi, and a brief review of the literature

The aim of this study is to present the cases of four neonates with hemorrhage within the cavum septi pellucidi (CSP). The sonographic findings of this rare location of intracranial hemorrhage, the related pathology and the possible underlying mechanisms are discussed, with a brief review of the literature. Three out of four of the neonates were premature and the fourth was a full-term infant with Down's syndrome. In all the patients the hemorrhage in the CSP was associated with severe intracranial hemorrhage.
