This presentation discusses the cytology of cerebrospinal fluid (CSF). CSF is normally clear, colorless, and transparent. It is produced in the cerebral ventricles and circulates in the spinal canal. A lumbar puncture or spinal tap is performed to examine the physical appearance and microscopic evaluation of CSF slides. The cytology technique involves centrifuging CSF samples onto slides, staining with Papanicolaou stain, and examining under a microscope. Normal CSF is acellular, while abnormal CSF may contain lymphocytes, monocytes, malignant or leukemia cells, indicating conditions such as meningitis, subarachnoid hemorrhage, or CNS malignancy. Cytology of CSF aids in the diagnosis of various

CYTOLOGY OF CSF
- 1. PRESENTATION ON “CYTOLOGY OF CSF” BY MAIMOON ZAFAR
- 2. The cerebrospinal Fluid [CSF] is clear colorless transparent The Tissue fluid present in the cerebral ventricles spinal canal
- 4. Lumbar puncture or spinal tap
- 5. Check Physical Appearance (gross) Slide Making (cytocentrifuge technique) Staining of slides Microscopic evaluation of slides
- 6. PHYSICAL APPEREANCE Normal • Crystal clear, colorless Abnormal • hazy, cloudy, turbid, milky, bloody, Xanthrochromic • Unclear specimens may contain increased lipids, proteins, cells or bacteria • Clots indicate traumatic tap • Milky – increased lipids • Oily – contaminated with x-ray • Xanthrochromic – Yellowing discoloration of supernatant (may be pinkish, or orange • Brown or Dark CSF –methemoglobin from a hematoma. • Green CSF --hyperbilirubinaria
- 8. CYTOCENTRIFUGE TECHNIQUE Use of centrifugal force to direct specimen onto cytoslides 2 slides are made cause sample is in small quantity
- 9. 1-2 drops sample + 1-2 drops of alcohol (95%) Spin at 600 rpm for 5 mins Remove and fix in alcohol
- 10. STAINING TECHNIQUE OF CSF SLIDES STAINING Papanicolaou stain done Harris heamtoxylin (nuclear stain) OG-6 (cytoplasm satin ) EA 50 (immature cells) Heamtoxlyin Water Acid water Water Lithium carbonate 70% ehtyl alcohol 80%ethyl alcohol 95%ehtyl alcohol OG-6 EA 50 95% ethyl alcohol Xylene phenol Xylene Cover slip/ DPX
- 11. Normal CSF is essentially acellular Entire smear should be evaluated for • abnormal cells • inclusions within cells • Clusters • Presence of intracellular organism
- 12. Types of cells Lymphocytes & monocytes / macrophages Malignant cells Ependymal cells (epithelial-like cells) Leukemia cells Neutrophils RBC WBC
- 13. Meningeal infections • viral,bacterial,fungal • Clear to cloudy Subarachnoid hemorrhage • ruptured cerebral aneurysm, or may result from head injury • Bloody CSF CNS malignancy • Brain tumors
- 14. Lymphocytes & monocytes / macrophages Mono / macro, segs and lymph
- 17. leukemic cells
- 18. • To confirm diagnosis of a disease • Evaluate for intracranial hemorrhage • Diagnose malignancies, leukemia • Investigate central nervous system disorders
- 19. THANK YOU FOR YOUR PATIENCE ANY QUESTIONS?
