title: Congenital cerebrospinal fluid-containing intracranial abnormalities: a sonographic classification.
abstract: Ultrasound is useful as a primary modality for diagnosis of complex nonhydrocephalic intracranial malformations. We present 10 cases of intracranial cerebrospinal fluid containing abnormalities that may be diagnosed by ultrasound. Congenital abnormalities presented include holoprosencephaly, hydranencephaly, agenesis of the corpus callosum with interhemispheric cyst, porencephaly, schizencephaly, and arachnoid cyst. Ultrasound may be used in the fetus or neonate in detecting and separating these abnormalities from hydrocephalus.
