Abstract

Allergic bronchopulmonary aspergillosis is an immunologic pulmonary disease characterised by proximal bronchiectasis with normal peripheral branchings and mucoid impactions in patients with asthma. The pathologic damage consists of mucoid impaction containing macrophages, several eosinophils, fungal hyphae, scaled-off epithelium (Curshman spirals) and calcium oxalate crystals. On CT, the mucoid impaction of the bronchial tree generally shows slightly hyperhydric density. The originality and peculiarity of our case is the presence of high-density mucoid impaction inside an atelectatic area.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Aspergillosis

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
