Study Notes
CSF Appearance and Causes
- Crystal clear CSF: normal appearance
- Hazy, turbid, or cloudy CSF: presence of microorganisms, white blood cells (WBCs), or high protein levels, indicating meningitis
- Bloody CSF: intracranial hemorrhage or traumatic tap
- Xanthochromic CSF (pink/orange/yellow): presence of hemoglobin, bilirubin, carotene, or melanin, depending on the length of contact between RBCs and CSF
- Clotted CSF: introduced clotting factors due to traumatic tap
- Pellicle: seen in tubercular meningitis, especially after overnight refrigeration
- Oily CSF: presence of radiographic contrast media
CSF Abnormalities and Disorders
- Meningitis: cloudy, turbid, or milky CSF, high WBC count, and elevated protein levels
- Traumatic tap: bloody CSF, clotted CSF, or presence of RBCs
- Intracerebral hemorrhage: bloody CSF
- Tubercular meningitis: pellicle formation, cloudy CSF, and high protein levels
