[Intracranial manifestation of lymphomatoid granulomatosis (Liebow's disease)].

An intracranial manifestation of lymphomatoid granulomatosis occurs in 20% of patients. In the case of a 56-year-old patient it is shown that a relative long period can pass from the first neurological symptoms to histological diagnosis by stereotactic brain puncture. Over 15 months, follow-up studies were performed using computed tomography and magnetic resonance.
