- Fig 1.
A 12-day-old neonate with GBS meningitis. Axial DWI demonstrates multifocal areas of diffusion restriction (ADC not shown) in the parenchyma, consistent with infarcts and cerebritis.
- Fig 2.
A 19-day-old neonate with E coli meningitis. A, Axial T2-weighted image demonstrates disproportionate enlargement of the lateral ventricles relative to the sulci, consistent with hydrocephalus. B, Axial DWI demonstrates areas of diffusion restriction (ADC not shown) in the ventricles (arrows), consistent with intraventricular purulent material. C, Axial T1-weighted postcontrast image demonstrates abnormal ependymal enhancement along the lateral ventricles (arrows).
