Technically,all of parts of the brain has fluid in it and on it. Without the fluid the brain would dry up and we would be unable to function it. Of course this liquid is the "ooze" that you can sometimes see on TV shows, and it is also blood that is circulating around the blood-brain barrier which keeps a large majority of blood out and it only allows a certain amount of fluid in or else our wonderful brains would drown.
Your brain is more than 90% fluid, so most of it is fluid filled.
ventricles
The ventricles are the fluid-filled cavities of the brain.
retrocerebellar arachnoid cysts are a cyst that is filled with fluid. The cyst in this case is located in the retrocerebellar area which is behind the cerebellum. The cerebellum is the part of the brain that has to do with motor function.
The vestibular sacs in your ears are filled with fluid, and the movement of fluid allows your "vestibular sense" to determine where your head is, and thus your general body position.
The cerebrospinal fluid protect the brain from any form of injury. The brain is covered with this fluid which will act as cushion.
The fourth ventricle is the space that fluid from the cerebral aqueduct flows. The cerebral aqueduct is a part of the ventricle system in the brain.

The ventricles are the fluid-filled cavities of the brain.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid
maybe
Those holes are called Ventricles, and together are part of the ventricular system. There are 4 ventricles altogether in the brain: 2 lateral ventricles (right and left) a third ventricle and a fourth ventricle (names are not very original, but thankfully easy to remember).
The ventricles are fluid filled cavities of the brain.
These are called ventricles.

spinal cord or brain are not solid because they have the system of canals which filled with fluid.
The empty half will fill with cerebral spinal fluid.
Ventricles
Semicircular canals: are the fluid filled structures in the ear, which are involved in balance.
