Why might a spinal tap be conducted on a person in a coma?

A spinal tap is conducted in coma cases if the CT and MRI scans are inconclusive and the doctor suspects infection of the spinal fluid from meningitis or other similar conditions. The scans are necessary to ensure that the pressure in the brain is not adversely affected by the tap, which could lead to more severe brain damage. Results of a spinal tap can help the doctor determine course of treatment.
