Are cysts in brain common and how does it feel like?

Please mention your query and its details properly.

The neuroimaging MRI findings of the left choroid plexus extend anteriorly past the foreman of Monro into the frontal horn of the left lateral ventricle. It is homogeneous in appearance with no obvious cyst or focal abnormality. However, as the differential diagnosis includes intraventricular hemorrhage, it possibly implies that the location of the choroid plexus (which is a normal structure in the ventricle of the brain) is slightly extending forward within the ventricle. Though it is showing its normal appearance in neuroimaging, Sometimes it is not very easily possible to say in MRI that it is normal choroid plexus only or has some bleeding associated because choroid plexus is full of blood vessels and sometimes are confused with blood in MRI. If there has been confusion between these two possibilities, a CT scan can be done as acute blood is better visualized in a CT scan. But as your wife is pregnant, it is not advisable to do a CT scan now (without any mandatory clinical indication) as a CT scan during pregnancy can give radiation exposure to the fetus.
