| Abstract: | Meningeal leukaemia, developed in 4 female patients with M4 or M5 leukaemia during a period of haematological remission. Polyradicular symptoms and signs dominated neurologically, but 3 patients also exhibited cranial nerve palsies. The neurological findings showed no reversal following intrathecal chemotherapy with normalization of liquor cytology. Patchy demyelinization in the region of the anterior spinal roots and of the proximal segments of the affected cranial nerves were responsible for the neurological features. Peripherally located streaky demyelinization of the olfactory bulb and of the optic chiasm were not found to cause any neurological manifestations. |
