Triphasic waves in a patient with tuberculous meningitis.
We report on the case of a 32-year-old woman with tuberculous meningitis (TBM) with electroencephalogram (EEG) output displaying triphasic waves (TWs). The EEG on day 8 revealed generalized slowing, frontal bilateral TWs, a background of 2Hz delta waves, and no epileptiform activity. The patient's condition improved slowly with antituberculosis chemotherapy treatment. A follow-up EEG on day 34 showed marked improvement, with no TWs, background activity improved to a 12Hz symmetric alpha wave pattern, and no epileptiform activity, as before. To our knowledge, this is the first report of TWs observed in a TBM case.
