Background. @entity715 is a life-threatening condition, which requires immediate therapy. Being infrequent in childhood, internal @entity49 is very rare in the neonate and has never been observed without concomitant occlusion of further dural sinuses. Case Description. We report a neonate born at term, who developed @entity410 on the third day of life after normal pregnancy and uneventful delivery. Ultrasound and CT disclosed bilateral intraventricular and @entity1779 with an unusual distribution for @entity548 . MRI disclosed @entity715 occlusion of the straight sinus and the internal cerebral veins with concomitant bleeding into the ventricles, the basal ganglia, thalamus and the periventricular hemispheres. The other sinuses were not affected. The clinical condition of the @entity1 improved after initiation of a low-dose heparin treatment with subsequent partial recanalization of the occluded vessels. The screening for risk factors disclosed an elevated lipoprotein (a) level, also present in both parents. Conclusion. @entity715 may be encountered in neonates and must be included in the list of differential diagnosis of perinatal intraventricular and @entity1779 . MRI allows the diagnosis even in the absence of widespread dural sinus occlusion. Low dose heparin may be a therapeutic option in these cases. This is the first report of neonatal internal @entity49 due to hereditary lipoprotein (a) level elevation, which must be included in the list of possible predisposing conditions.
