The ventricles are fluid-filled chambers in the brain. The characteristic neuroimaging features on computed tomography (CT) and magnetic resonance imaging (MRI) of PVL are summarized in Table 4. Page highlights. 2023 American Medical Association. The damage creates "holes" in the brain. Premyelinating oligodendrocytes, which predominate in periventricular regions during the window of vulnerability to PVL (24 to 34 postconceptional weeks), are the targets of this free radical injury, and suffer cell death. 'MacMoody'. PVL | Disability charity Scope UK 1983;71(5):794-797. Among the recent findings directly in human postmortem tissue is that immunocytochemical markers of lipid peroxidation (hydroxy-nonenal and malondialdehyde) and protein nitration (nitrotyrosine) are significantly increased in PVL. Magnetic resonance imaging (MRI) is much more effective at identifying PVL, but it is unusual for preterm infants to receive an MRI unless they have had a particularly difficult course of development (including repeated or severe infection, or known hypoxic events during or immediately after birth). Diffuse white matter lesions of the cerebral hemispheres of the brain, accompanied by softening and spreading to the central and subcortical areas are more likely DFL, PHI and ME.[1]. The site is secure. [6] These developmental delays can continue throughout infancy, childhood, and adulthood. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5745826/).

But thiamine deficiency by severe malabsorption was the probable cause of this neurologic complication. The disorder is caused by a lack of oxygen or blood flow to the periventricular area of the brain. Many infants with PVL eventually develop cerebral palsy. This phenomenon is believed to result from transsynaptic degeneration and has been noted to be associated with the lateral geniculate nucleus in pediatric populations. Periventricular leukomalacia (PVL) is a softening of white brain tissue near the ventricles. Babies with PVL generally have no outward signs or symptoms of the disorder, but they are at risk for: PVL may be accompanied by a hemorrhage or bleeding in the periventricular-intraventricular area and can lead to cerebral palsy.
