    This study describes the radiological features of pulmonary aspergilloma in 49 patients, primarily those with underlying tuberculosis. Key findings include common cavity characteristics and the utility of advanced imaging techniques for diagnosis.

    Area of Science:

    • Radiology
    • Pulmonology
    • Infectious Diseases

    Background:

    • Pulmonary aspergilloma is a fungal infection often complicating pre-existing lung conditions.
    • Pulmonary tuberculosis (PTB) is a significant underlying disease associated with aspergilloma development.

    Purpose of the Study:

    • To describe the radiological appearances of pulmonary aspergilloma.
    • To correlate imaging findings with clinical characteristics and diagnostic confirmations.

    Main Methods:

    • Retrospective review of 49 cases of pulmonary aspergilloma over six years.
    • Analysis of radiological features including distribution, cavity characteristics, and morphology.
    • Correlation with underlying diseases, particularly pulmonary tuberculosis.
    • Confirmation of diagnosis using serum precipitins against Aspergillus.

    Main Results:

    • Pulmonary tuberculosis was the predominant underlying disease in all 49 patients.
    • Common radiological findings included upper zone distribution, large cavities, thick walls, and pleural thickening.
    • Aspergillomas were predominantly round or oval, with observed positional movement in many cases.
    • Radiological diagnosis was confirmed by serum precipitins in 44 out of 49 cases.

    Conclusions:

    • Pulmonary aspergilloma in this cohort was strongly associated with underlying pulmonary tuberculosis.
    • Specific radiological features can aid in the diagnosis of aspergilloma.
    • Advanced imaging techniques and serological tests are crucial for confirming the diagnosis.
