[Spontaneous frotobasal cerebrospinal fluid fistula].
After dealing in detail with the literature appeared since 1888, 3 observations by the author are discussed. These cases were congenital fissurations on the frontal base of the skull. Some cases developed clinical phenomena with increases of the intracranial pressure (convexity meningioma). The diagnosis is defined in a strict manner. All forms of direct arrorions by frontobasally located tumours or in combination with hyhpophyseal tumours as well as craniopharyngiomas are left out of consideration. They cannot be considered as spontaneous liquor fistulas. The well-known diagnostic and therapeutic measures are dealt with briefly.
