pseudomeningitis (uncountable)

1. A condition that resembles, but is not in fact, meningitis.
   • 1897, Thomas Lathrop Stedman, Twentieth Century Practice: Diseases of the nervous system, page 410:

     […] who recognized the condition at a time when meningitis was considered almost synonymous with hydrocephalus. The term is now disappearing from medical literature and these cases are more often called pseudomeningitis. As we have already said, the symptom complex of pseudomeningitis develops sometimes with acute fevers such as rheumatism, typhoid fever, etc.
