A cerebrospinal fluid leak (CSFL) is a medical condition when the cerebrospinal fluid of a person leaks out of the dura mater. This can be caused by several reasons, including spontaneous cerebrospinal fluid leak, post-surgical lumbar puncture (iatrogenic), physical trauma, etc. While high CSF pressure can make reclining unbearable, low CSF pressure due to a leak is often relieved somewhat by maintaining a supine position.
Famous quotes containing the words fluid and/or leak:
“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
—Ralph Waldo Emerson (1803–1882)
“The office ... make[s] its incumbent a repair man behind a dyke. No sooner is one leak plugged than it is necessary to dash over and stop another that has broken out. There is no end to it.”
—Herbert Hoover (1874–1964)
