[Thrombosis of A. cer media in Werlhof's disease (author's transl)].

Apoplectiform incidents, particularly in young patients, can be an exceptional problem for neurologists and internists, even when every technical aid for diagnosis is available. This paper is intended to point out that even in a basic disease like Werlhof's disease, which is accompanied by an increased hemorrhagic tendency, several additive or potentiating unfavorable factors can produce a thrombosis in the region of a cerebral vessel and for this reason they should be included in the differential diagnostic considerations.
