The tracer will diffuse up the spinal column and into the intracranial ventricles and the subarachnoid spaces around the brain.
32.
Trauma can cause the fluid within a cyst to leak into other areas ( e . g ., subarachnoid space ).
33.
Between the arachnoid and the underlying pia mater is the subarachnoid space, which is filled with cerebro-spinal fluid ( CSF ).
34.
This is a condition generally seen in infants and involving enlarged fluid spaces or subarachnoid spaces around the outside of the brain.
35.
Another sign of ulegyria that is visible on an MRI scan is the presence of a widened subarachnoid space, signifying cortex atrophy.
36.
In pituitary apoplexy the results are typically normal, although abnormalities may be detected if blood from the pituitary has entered the subarachnoid space.
37.
Infiltration from the subarachnoid space into the spinal cord occurs primarily along the perivascular tissues that surround blood vessels at the brain entrance.
38.
There is connection from the subarachnoid space to the bony labyrinth of the inner ear making the cerebrospinal fluid continuous with the perilymph.
39.
Shunt surgery, usually performed by lumboperitoneal ( LP ) shunt, which connects the subarachnoid space in the lumbar spine with the peritoneal cavity.
40.
If a membrane prevents CSF flow between the ventricle and the subarachnoid space, then an incision is made in the membrane as well.
