Abstract:
When using CT in assessment of hydrocephalus affected different ages from
one-day to 75 years, the determining factor for or against the implantation of a
shunt is the degree of ventricular dilatation. The researcher has devised a
standardized method of estimating this, the use of which has been shown to
achieve consistently successful results. Dilatation was determined using the
ventricular ratio from the axial CT scan at the mid-portion of the bodies of the
lateral ventricles, showing the greatest ventricular dilatation.
According to this method, it was shown that some cases of congenital
hydrocephalus the cause remains unknown in this study, stage of fourth
ventricles shows the high percent was 56% for the people that are not dilated,
while stage of Third ventricle shows the high percent was (88%) for the people
that are dilated. It was, as well, shown that type of hydrocephalus among
population of the study was equal 50% for the communication and 50% for the
non communication.
It’s recommended that for unknown cause of hydrocephalus there should be
further imaging investigations such as MRI and CT clinics especially in
hospitals where this study carried out.
In conclusion, some cases of congenital hydrocephalus the cause remains
unknown in this study.
