An ultrasound does not provide information about a brain tumor.
It is produced in the brain by modified ependymal cells in the choroid plexus.
Cranial Ultrasound
Neurosonography is a small, specialized section of ultrasound, frequently used in the NICU on premature babies. Images of the brain are able to be produced on premature and young babies due to the skull not being fully fused together yet, therefore allowing the ultrasound beam to reach the brain tissue. Neurosonography is also used before the baby is born, and still in the mother's womb. Once the skull has fused, transcranial ultrasound is still possible to an extent, through very small openings within and around the skull. This area of ultrasound is frequently used in high risk pediatric and specialty hospitals, such as St. Jude Children's research hospital. Using ultrasound on the brain of a fully fused skull is more challenging because an ultrasound beam cannot penetrate through bone. However, with skill and knowledge, it is possible to obtain brain images.
I believe you're talking about sonography. The best known form of which is ultrasound for pregnant women. However, there are many other uses of ultrasound. It is often used to conduct an echocardiogram (an image of the heart), as well as looking for bleeds in the brain.
The structures in the brain responsible for producing and circulating cerebrospinal fluid are the choroid plexus, located within the ventricles of the brain. Cerebrospinal fluid is produced in the choroid plexus and then circulates around the brain and spinal cord, providing essential nutrients and protection for the central nervous system.
The Frontal Cortex
The brain's structures are shown in this video.
The main structures of the brain are the cerebrum (the fore brain), the cerebellum (the hind brain), the brain stem.
