Case report: Disseminated cryptococcus gattii in an immunocompetent patient

Area of Science:

• Mycology
• Infectious Diseases
• Immunology

Background:

• Cryptococcosis is an opportunistic fungal infection caused by Cryptococcus species.
• It affects both immunocompromised and immunocompetent individuals.
• Disseminated disease, particularly cryptococcal meningitis, has high mortality rates.

Observation:

• A case of a healthy, immunocompetent male with a six-month history of weight loss, cough, hemoptysis, and a lung mass is presented.
• Differential diagnoses included Tuberculosis, bacterial/fungal pneumonia, and lung carcinoma.
• The patient was diagnosed with disseminated Cryptococcus gattii infection, a rare occurrence.

Findings:

• Risk factors identified were a history of smoking and recent travel to Central Africa.
• Disseminated Cryptococcus gattii infection is rare in immunocompetent hosts.
• The case underscores the need to consider fungal pathogens in respiratory and neurological presentations.

Implications:

• Fungal infections should be considered in patients with respiratory or neurological symptoms, irrespective of immune status.
• Thorough travel history is crucial for diagnosing infections with endemic atypical pathogens.
• Recognizing cryptococcosis is vital for managing morbidity and preventing complications.
