A case of neoplastic angioendotheliosis demonstrating unusual manifestations is reported. A 56-year-old male showed recurrent attacks of neurological symptoms including paraplegia, brain-stem symptoms, tonic seizures, aphasia, apraxia and cortical blindness over 2 years. The EEG disclosed transient, periodic, lateralized, epileptiform discharges. Brain CT scan revealed low-density areas mainly in the white matter. Other laboratory examinations were negative except for CSF protein fractions. Post-mortem examination disclosed remarkable intravascular proliferation of atypical cells in the CNS with prominent proliferation of blood vessels and softening. Other organs were not affected, which suggested that the atypical cells had a high affinity to CNS blood vessels.
