The case of a 53-year-old female with a Philadelphia-chromosome (Ph')-positive chronic myeloid leukemia (CML) is reported. In this patient, a first lymphoid blast crisis developed after a chronic period of 20 months. Treatment with vincristine and prednisone was successful. A few weeks later she presented with meningeal leukemia with lymphoid blastic cells in CSF and a facial nerve palsy, while the peripheral blood showed the typical picture of CML. Meningeal leukemia was successfully treated with cranial irradiation and intrathecal chemotherapy. Later on, a second lymphoid blast crisis (blasts of "common acute leukemia" type) was observed. Again, chemotherapy with vincristine and prednisone was successful. After 2 1/2 weeks, however, a third lymphoid blast crisis developed. At this moment, Ph'-chromosome was undetectable in unstimulated cells of the peripheral blood. The question of an additional leukemia is discussed.

Between 1971 and 1992 neuropathological examinations were performed in 316 patients having died of leukaemia. Among them 73 had acute lymphoid leukaemia, 134 acute myeloid leukaemia, 49 chronic lymphoid leukaemia and 60 chronic myeloid leukaemia. Meningeal leukaemia, which had been a frequent pathological complication at the beginning of the examination period, later had become rarer. The study made it possible to define further neurologic complications, the characteristic neuropathological changes of the different types and some subtypes of leukaemia and to draw clinical consequences. The incidence of cerebral "leukaemic nodules" was twelve times higher in the myeloid than in the lymphoid leukaemias, this may be the explanation for the fact that central nervous system haemorrhage was more frequent in the myeloid types. Subdural haematoma can primarily be expected in acute myeloid leukaemia. The neuropathologic features of chronic lymphoid leukaemia were particular, as no "leukaemic nodules" developed, and meningeal leukaemia was a rare event; at the same time, it was related with the highest incidence of infiltration of the dura mater and the sciatic nerve.
