    — Not lined by gray matter but lined by normal or gliotic white matter
    — Can communicate with ventricle or cortical surface
  • DDX: Schizencephaly, polymicrogyria

Radiology Cases of Porencephaly Due to Periventricular Leukomalacia

US and MRI of periventricular leukomalacia and porencephaly
Coronal US of the brain on day of life 3 (above left) shows bilateral increased periventricular echogenicity. Coronal US of the brain on day of life 30 (above right) shows the previously seen areas of increased periventricular echogenicity to have undergone cystic transformation bilaterally. Axial T2 MRI without contrast of the brain at 3 months of age (below) shows an irregular contour and appearance to the occipital horns of the lateral ventricles.
