A case of peculiar form of Klüver-Bucy syndrome is reported. The diagnosis of viral meningoencephalitis was made by the clinical features and by cerebrospinal fluid and histological examination (brain byopsy). The computed tomography and electroencephalographic aspects are analysed. The viral meningoencephalitis was possibly herpetic in nature (herpes simplex virus). The patient here concerned, a woman aged twenty-one years old, during the clinical course of the disease showed insatiable appetite, psychic blindness, oral tendencies, aberrant sexual behavior and hypermetamorphopsia (Klüver-Bucy syndrome). The significance of these features is discussed.
