Pyogenic meningitis: sonographic evaluation.

ABSTRACT

Forty infants with proven pyogenic meningitis were evaluated by real time cranial sonography. A spectrum of sonographic abnormalities was observed which included echogenic sulci, focal or diffuse increase in parenchymal echoes, ventriculitis, ventriculomegaly with or without aqueductal block, subdural collection, parenchymal infarcts, abscess and subdural empyema. There were two infants with normal sonogram while encephalomalacia was seen in another two patients. An excellent correlation was observed between clinical profile, cerebrospinal fluid biochemistry and sonographic findings.
