With increasing awareness of CT’s irradiation risk, I thought I would review a classic 2001 article from the New England Journal of Medicine. Head CT’s previously were commonly performed prior to all lumbar punctures (LP) to rule-out meningitis. When can you safely go straight to an LP without imaging?
Caveat: This review only applies to those patients in whom you suspect meningitis. This does not apply to those being worked up for subarachnoid hemorrhage.
