Neurosonography of cranial lesions in infants

Since early 1980's, high resolution ultrasound has been world-widely used for detection of cranial lesions in infants but not widely used in Korea. Authors prospectively analysed ultrasonographic findings of 107 cases which were confirmed by CT, autopsy or follow-up studies as supplement. The distribution of 107 cases was intracranial hematoma 40 cases, hydrocephalus 36 cases, hypoxic-ischemic encephalopathy 10 cases, porencephalic cyst 5 cases, cephalhematoma 5 case, agenesis of corpus callosum 4 cases, medulloblastoma 2 cases and each one case of A-V malformation, intraventricular cyst, Dandy Walker cyst, lipoma and hydranencephaly. We could conclude that neurosonography of infants was very useful and effective method in detection of cranial lesions such as intracranial hematoma, especially germinal matrix hemorrhage or intraventricular hemorrhage in preterm infant, hydrocephalus, hypoxic-ischemic encephalopathy and congenital anomalies.
