[Acute hemorrhagic meningoencephalitis due to rubella-infection in acute lymphatic leukemia (author's transl)].

We observed a fatal meningoencephalitis in a patient who suffered from acute lymphatic leukemia. The infection occurred after complete bone marrow remission. As the cause of this complication we discovered a rubella-infection, whose beginning had been several weeks ago. Relations to several forms of rubella-encephalitis in otherwise healthy patients are discussed and pathogenetical conclusions are made.
