Periventricular Leukomalcia Vs Normal Periventricular Blush
- Normally the periventricular area can be slightly echogenic.
- Early PVL appears as periventricular increased echogenicity ( PV area- Watershed area in premature babies and Posterior Parieto-Occipital areas are watershed areas in Term Infants).
To differentiate remember this --
"Echogenicity that is less echogenic than the adjacent choroid plexus is considered to be normal.Coarse, echogenic areas equal to or greater than that of the adjacent choroid are suspicious for PVL. When in doubt, scanning through the posterior fontanelle will eliminate the normal periventricular blush, whereas the pathological echogenicity of PVL will persist."
