neonatal brain 2 Flashcards
premature baby is born before
37 weeks
that two parts of the brain are prominent in immaturee brain
cystic cavum septum pellucidum (CS) and cavum vergae (CV) are prominent in the premature infant
what is cavum vergae
extension of CSP, persistence of the embryological fluid-filled space between the leaflets of theseptum pellucidumand is a common anatomical variant
difference seen in brain parenchyma of immature brain
it is smooth due to underdeveloped gyri and sulk
what is a marker of extreme prematurity
wide open sylvan fissures
if a peritrigonal blush/halo persists it could be a sign of
periventricular leukomalacia (PVL)
left lateral ventricle bigger than right is
normal variant
bilateral cysts by the front horns of the lateral ventricle is
normal vaiant
major cause of morbidity and mortality in premature infant
intracranial hemorrhage
common place for intracranial hemorrhage to occur
Germinal Matrix Intraventricular Hemorrhage (GMH)
when does Germinal Matrix Intraventricular Hemorrhage usually occur
within 3 days of life in premature infant
what is the germinal matrix
fetal structure, a fine network of blood vessels and primitive neural tissue located in subepindymal region of lateral ventricles
thin epithelium-like lining of theventricular systemof thebrainand thecentral canalof thespinal cord.
ependyma
4 classifications of intracranial hemorrhage (ICH)
1: subepindymal hemorrhage
2: IVH without ventricular dilation
3: IVH with ventricular dilation
4: intraparenchymal hemorrhage with or without ventricular dilation
grade 2 hemorrhage appearance
no dilation of ventricle
clot can adhere to the choroid plexus making it look irregular and thick
blood mostly collects in the occipital horn and will appear as echogenic material
