Overview
The differential diagnosis of fungal meningitis includes a range of medical conditions that can be broadly classified into infectious and non infectious. The cerebrospinal fluid analysis and radiological findings help distinguishing fungal meningitis from other etiologies.
Differential Diagnosis
- Meningeal infection
- Bacterial meningeal infection
- Protozoal meningeal infection
- Helminthic meningeal infection
- Viral meningeal infection
- Parameningeal infection
- Non infectious causes
- Behçet's syndrome
- Chronic benign lymphocytic meningitis
- Chemical meningitis
- Drug hypersensitivity
- Isolated granulomatous angiitis of the nervous system
- Granulomatosis with polyangiitis (Wegener's)
- Malignancy
- Mollaret's meningitis
- Sarcoidosis
- Systemic lupus erythematosus
- Vogt-Koyanagi-Harada syndrome[1]
