title: The spectrum of leukomalacia using cranial ultrasound.
abstract: The spectrum of leukomalacia using cranial ultrasound is discussed. Transient densities not evolving into cystic lesions may represent a mild degree of leukomalacia when persisting for at least a week. A unilateral parenchymal density may be due to bleeding into an ischaemic area, but can also be due to a venous infarction. Cystic leukomalacia can be confidently diagnosed using appropriate equipment and performing sequential scans. A distinction should be made between cysts in the periventricular white matter and cysts in the deep white matter, as the latter carries a higher risk for cerebral visual impairment. Careful ophthalmological examination of these infants will enable us to identify infants with cerebral visual impairment during the first few months of life, allowing the use of special programs aimed at promoting visual development.
