Cryptococcosis Symptoms:
- Headache
- Fever
- Neck stiffness
- Nausea and vomiting
- Confusion or changes in mental status
- Blurred vision
- Chest pain or shortness of breath
- Cough
- Skin lesions, especially in immunocompromised individuals
It’s important to note that the symptoms of cryptococcosis may vary depending on the affected organ system and the patient’s immune status. Therefore, a high index of suspicion is required to include cryptococcosis in the differential diagnosis.
Cryptococcosis Diagnosis Guidelines:
The diagnosis of cryptococcosis involves a combination of clinical evaluation, laboratory tests, and imaging studies. Several guidelines and criteria have been established to aid in the accurate diagnosis of this fungal infection.
| Evidence-based Diagnosis Guidelines for Cryptococcosis | Key Parameters |
