[Sonographic follow-up studies in purulent meningitis and its complications in infancy].

In 29 newborns and 18 infants ill with meningitis the following characteristic signs visible by sonographic examination of the brain mostly indicated complications: increase of the leptomeningeal echogenicity, increase of the periventricular echogenicity in ventriculitis, alterations of the configuration of the ventricles, typical echos in the CNS-fluid by increased cell and protein content, alterations of the Plexus chorioideus caused by inflammation, membranes in the enlarged ventricular system. In the first year of life the sonographic examination of the brain is ideal for early diagnosis of possible complications in meningitis to change the therapeutic management without any loss of time.
