Summary

Immature hematopoietic cells in cerebrospinal fluid (CSF) of children are likely bone marrow contaminants, not signs of infection or leukemia. Pathologist review of CSF samples is crucial for accurate diagnosis and appropriate care.

Area of Science:

  • Pediatric Hematology
  • Clinical Pathology
  • Cerebrospinal Fluid Analysis

Background:

  • Immature hematopoietic cells are occasionally found in cerebrospinal fluid (CSF) samples.
  • Distinguishing these cells from pathological findings is critical for patient management.

Purpose of the Study:

  • To identify the origin of immature hematopoietic elements in pediatric CSF samples.
  • To emphasize the importance of recognizing bone marrow contamination in CSF analysis.

Main Methods:

  • Analysis of Wright-stained cytocentrifuge preparations of CSF.
  • Lumbar puncture procedures performed on infants and children.

Main Results:

  • Immature hematopoietic elements were identified in 8 CSF samples.

  • These elements were likely contaminants from vertebral bone marrow.

    • Conclusions:

    • Nucleated cells in pediatric CSF are often bone marrow contaminants, not indicative of infection or leukemia.
    • Recognition of contamination is vital for immediate child care, with transient headache being the only identified sequela.
    • Pathologist review of all pediatric CSF cytocentrifuge preparations is recommended due to potential bone marrow contamination.
