Periventricular leukomalacia (PVL) is a term used to describe cerebral white matter injury with both focal and diffuse components. It is important to differentiate PVL from the following major white matter lesions in the cerebral hemispheres: edematous hemorrhagic leukoencephalopathy (OGL), telentsefalny gliosis (TG), diffuse leukomalacia (DFL), subcortical leukomalacia (SL), periventricular hemorrhagic infarction (PHI), intracerebral hemorrhage ( ICH), multicystic encephalomalacia (ME), subendymal pseudocyst. Only 7.8% of patients who had no identified cerebrovascular risk factors and who reported no cerebrovascular symptoms had these MRI periventricular lesions; 78.5% of patients with a history of cerebrovascular risk factors and . Children and adults may be quadriplegic, exhibiting a loss of function or paralysis of all four limbs. Children with PVL should receive regular medical screenings to determine appropriate interventions.

The ventricles are fluid-filled chambers in the brain. Because the vascular supply of the periventricular region of the brain in utero remains immature late into term, PVL may arise from neonatal hypoglycemia, hypoxia, seizure, or infection in the third trimester or perinatally5,6. Longitudinal follow-up with repeat visual field and OCT are helpful in differentiating PVL related optic atrophy from normal tension glaucoma. The gait of PVL patients with spastic diplegia exhibits an unusual pattern of flexing during walking.[16].

This range corresponds to the severity of PVL, which can also be quite variable. Periventricular leukomalacia can lead to physical and mental development issues. However, neuro-ophthalmic presentation of PVL is highly variable. Consequently, functional defects in patients with PVL are highly dependent on location of insult. Federal government websites often end in .gov or .mil. and apply to letter. The white matter (leuko) surrounding the ventricles of the brain (periventricular) is deprived of blood and oxygen leading to softening (malacia). [5] No agencies or regulatory bodies have established protocols or guidelines for screening of at-risk populations, so each hospital or doctor generally makes decisions regarding which patients should be screened with a more sensitive MRI instead of the basic head ultrasound.
