| lumbar puncture |
Cerebro-spinal fluid, the fluid that surrounds the brain and spinal cord, can be removed with a needle that is inserted into the spine in the lower back. Examination of the fluid can reveal infection (such as meningitis due to bacteria or tuberculosis) or blood from hemorrhage. In some patients with subarachnoid hemorrhage, CT scans are normal, and lumbar punctures are necessary to demonstrate blood from the hemorrhage that has spread throughout the cerebro-spinal fluid.

A diagnostic procedure that uses a hollow needle (canula) to penetrate the spinal canal at the level of third-fourth or fourth-fifth lumbar vertebrae to remove cerebrospinal fluid for analysis. This procedure is used to examine the cerebrospinal fluid for changes in composition that are characteristic of MS (eg, elevated white cell count, elevated protein content, the presence of oligoclonal bands).
