Hemorrhage and cyst development in the cavum septi pellucidi and cavum Vergae. Report of three cases.

Three newborn preterm infants are reported in whom sonography and CT showed abnormalities of the cavum septi pellucidi and cavum Vergae. Hemorrhage into the cavum was noted in two and an acquired cyst developed in the third. These lesions are rare and appear to be of little clinical significance in the three reported infants. All three had associated intraventricular hemorrhage.
