On chest X-ray and CT, pulmonary aspergillosis classically manifests as a halo sign, and later, an air crescent sign. [24] In hematologic patients with invasive aspergillosis, the galactomannan test can make the diagnosis in a noninvasive way. Galactomannan is a component of the fungal wall. [13]
Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [ 1 ] Aspergillus penicillioides is typically found in indoor air, house dust , and on substrates with low water activity , such as dried food, papers affected by foxing , and inorganic objects such as binocular lenses.

Histopathology of aspergilloma, H&E staining. The most common organ affected by aspergilloma is the lung. Aspergilloma mainly affects people with underlying cavitary lung disease such as tuberculosis, sarcoidosis, bronchiectasis, cystic fibrosis and systemic immunodeficiency.
Allergic bronchopulmonary aspergillosis; Other names: ABPA, Hinson-Pepys disease. The chest radiograph of an allergic bronchopulmonary aspergillosis patient shown with left-sided perihilar opacity (blue arrow) along with non-homogeneous infiltrates (transient pulmonary infiltrates indicated by red arrows) in all zones of both lung fields.
The distinction is important because cystic lesions are unlikely to be cancer, while cavitary lesions are often caused by cancer. [3] Diagnosis of a lung cavity is made with a chest X-ray or CT scan of the chest, [2] which helps to exclude mimics like lung cysts, emphysema, bullae, and cystic bronchiectasis. [5]
Aspergillus species are highly aerobic and are found in almost all oxygen-rich environments, where they commonly grow as molds on the surface of a substrate, as a result of the high oxygen tension. Commonly, fungi grow on carbon-rich substrates like monosaccharides (such as glucose) and polysaccharides (such as amylose).
An opportunistic infection is an infection caused by pathogens (bacteria, fungi, parasites or viruses) that take advantage of an opportunity not normally available.These opportunities can stem from a variety of sources, such as a weakened immune system (as can occur in acquired immunodeficiency syndrome or when being treated with immunosuppressive drugs, as in cancer treatment), [1] an altered ...
