    Summary

    Central nervous system leukemia, particularly in chronic myelogenous leukemia, presents with mental and cranial nerve issues. This post-mortem study found no diagnostic criteria, with hemorrhage being a common pathological finding.

    Area of Science:

    • Neurology
    • Hematology
    • Pathology

    Background:

    • Leukemia can affect the central nervous system (CNS), complicating patient care.
    • Understanding CNS leukemia's clinical and pathological features is crucial for diagnosis and management.

    Purpose of the Study:

    • To investigate the clinical and pathological characteristics of central nervous system leukemia.
    • To identify common signs, symptoms, and autopsy findings in CNS leukemia.

    Main Methods:

    • Post-mortem examination of 18 cases with central nervous system leukemia.
    • Clinical and pathological data analysis.

    Main Results:

    • Central nervous system leukemia occurred most frequently in chronic myelogenous leukemia (38.8%).

  • Common clinical manifestations included mental status disturbances and cranial nerve dysfunction; cerebrospinal fluid analysis was often normal.
  • Frequent pathological findings included parenchymal hemorrhage (61%), subarachnoid hemorrhage (55%), and meningeal infiltrates (44%).

    • Conclusions:

    • Central nervous system leukemia lacks specific diagnostic criteria and can occur at any disease stage.
    • Hemorrhage and infiltrates are key pathological hallmarks of CNS leukemia.
    • Median survival after CNS involvement was short (21 days).
