[Herpetic meningo-encephalitis : emergency E.E.G. diagnosis and neurosurgical treatment (author's transl)].

Reporting two cases of true herpetic encephalitis, the authors insist on the great diagnostic value of some nearly constant, but transitory, aspects of localised periodic waves in the E.E.G. An emergency cerebral (usually temporal) resection is then advised. Thus focal infection is reduced and intra-cranial hypertension is prevented. Virologic and electron microscopic studies of the cortical specimen establish with certainty the diagnosis of herpetic encephalitis.
