Overview
Other Diagnostic studies
- India ink or fungal wet mount of CSF will demonstrate a (budding yeast).
- Mucicarmine stain provides specific staining of the polysaccharide cell wall.
- Antigen detection in CSF is useful for the diagnosis of cryptococcal meningitis.
- Cryptococcus neoformans can be cultured from sputum or bronchoalveolar lavage or transbronchial lung biopsy specimen or pleural fluid or pleural biopsy specimen in patients with pulmonary cryptococcosis.[1]
CSF Analysis
Cryptococcal meningitis may be differentiated from other causes of meningitis by cerebrospinal fluid examination as shown below:[2][3][4][5][6]
| Cerebrospinal fluid level | Normal level | Bacterial meningitis[5] | Viral meningitis[5] | Cryptococcal meningitis | Tuberculous meningitis[7] | Malignant meningitis[2] |
|---|---|---|---|---|---|---|
| Cells/ul | < 5 | >300 | 10-1000 | 10-500 | 50-500 | >4 |
| Cells | Lymphocyte:Monocyte 7:3 | Granulocyte > Lymphocyte | Lymphocyte > Granulocyte | Lympho.>Granulocyte | Lymphocytes | Lymphocytes |
| Total protein (mg/dl) | 45-60 | Typically 100-500 | Normal or slightly high | High | Typically 100-200 | >50 |
| Glucose ratio (CSF/plasma)[3] | > 0.5 | < 0.3 | > 0.6 | <0.3 | < 0.5 | <0.5 |
| Lactate (mmols/l)[4] | < 2.1 | > 2.1 | < 2.1 | >3.2 | > 2.1 | >2.1 |
| Others | ICP:6-12 (cm H2O) | CSF gram stain, CSF culture, CSF bacterial antigen | PCR of HSV-DNA, VZV | CSF gram stain, CSF india ink | PCR of TBC-DNA | CSF tumor markers such as alpha fetoproteins, CEA |
