Females' brains showed evidence of inflammation, and males' lateral ventricles
were 2-3 times larger than normal.
There are multiple abnormal enhancing vessels centered in the midbrain, right thalamus, third and lateral ventricles
(Figures 1-4) compatible with arteriovenous malformation.
Their brains also had markedly larger lateral ventricles
-- empty spaces containing cerebrospinal fluid -- compared with other mice.
A complete surgical resection is more commonly possible with lesions located in the lateral ventricles
, with fourth ventricular locations often treated with subtotal resections.
A periventricular rim, T2 hyper, T1 hypointense, was seen along the lateral ventricles
(Figs 2a and 2b).
That report stated, inter alias "The lateral ventricles
are enlarged, including the atria, occipital horns and body.
They may circulate freely throughout the cerebrospinal fluid (CSF) pathways or become attached to the ependyma anywhere in the ventricles, but their predilection is for the occipital horn of the lateral ventricles
and fourth ventricle.
Kuo decided to study these cells because the lateral ventricles
in the brain, where adult neural stem cells reside, are also the last area of a developing brain that grows ependymal cells.
Neurogenesis is the production of new neurons and continues throughout the adult mammalian lifespan in the subventricular zone of the lateral ventricles
and the subgranular zone of the hippocampal dentate gyms (DG).
Enlargement of the cerebral lateral ventricles
is known to occur as a consequence of brain atrophy in Alzheimer's disease (AD).
Fetal ventriculomegaly was defined as dilated lateral ventricles
with a mean transverse diameter of 10 mm or greater.
Transventricular: skull, midline, falx, cavus septi pellucidi, lateral ventricles
, head circumference, ventricular atrium
