Pulmonary aspergilloma is commonly associated with tuberculosis.

She also suffered from type II diabetes mellitus. Chest examination showed vesicular sound decreased in third to fourth left intercostal spaces.

This finding was confirmed by the contrast-enhanced CT scan of the chest and continued to lobectomy. Histological examination confirmed the presence of a granuloma formation, necrosis, hyphae structure with the conclusion of Aspergillus sp. infection.
