Sonographic recognition of multiple cystic encephalomalacia.

Multiple cysts in both hemispheres were detected in four children under 1 year of age by real-time sonographic sector scanning. These cysts, typical of multiple cystic encephalomalacia, followed viral encephalitis in two, bacterial meningitis in one, and bacterial meningitis superimposed on intracerebral hemorrhage in one. The diagnosis of multiple cystic encephalomalacia, which has a grave prognosis, is readily made with high-resolution real-time sonography.
