Thoracic cryptococcosis: immunologic competence and radiologic appearance.

M B Khoury, J D Godwin, C E Ravin

    Summary

    Pulmonary cryptococcosis is increasingly diagnosed in both immunocompromised and non-compromised individuals. Radiographic findings differ between these groups, with compromised hosts showing more complex lung abnormalities.

    Area of Science:

    • Infectious Diseases
    • Pulmonology
    • Radiology

    Background:

    • Cryptococcosis is a serious pulmonary infection with rising incidence.
    • It affects both immunocompromised and seemingly healthy individuals.
    • Understanding its varied presentation is crucial for diagnosis.

    Purpose of the Study:

    • To review cases of pulmonary cryptococcosis.
    • To compare radiographic findings in compromised versus non-compromised hosts.
    • To highlight diagnostic patterns.

    Main Methods:

    • Retrospective review of 24 proven cases of pulmonary cryptococcosis.
    • Categorization of patients into immunocompromised (15 cases) and non-compromised (9 cases) groups.
    • Analysis of radiographic patterns associated with each group.

    Main Results:

    • Non-compromised hosts typically presented with peripheral pulmonary nodules.
    • Immunocompromised hosts showed diverse radiographic findings: nodules, consolidation, bronchopneumonia, cavitation, and mixed patterns.
    • Adenopathy, cavitation, and pleural effusions were exclusive to immunocompromised patients.

    Conclusions:

    • Radiographic presentation of pulmonary cryptococcosis varies significantly based on host immune status.
    • Peripheral nodules suggest cryptococcosis in non-compromised individuals.
    • Complex abnormalities like cavitation and effusion indicate a compromised host.
