Develop depends upon the size and the subarachnoid space around the brain tissue ) is typically characterized clinically by and. Under ultrasound guidance, a 22-gauge spinal needle was introduced through the uterine wall, through the fetal scalp and into the enlarged extra-axial CSF space of the fetal head. It has been described as a variation of normal development of the brain, whereby there is a transient accumulation of cerebrospinal fluid in the frontal region. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. Nick Fox of University College London, U.K., noted there is no guarantee that the changes seen are due to aging or non-Alzheimer's pathology. These can be visualized on MRI or CT imaging.
