Abstract

Aspergillus can cause a wide spectrum of pulmonary complications. It may colonize pre-existing cavities to form mycetomas. In asthmatic patients it may lead to a hypersensitivity reaction involving eosinophilic infiltration of the bronchial wall and mucoid impaction (a condition called allergic bronchopulmonary aspergillosis) or granulomatous inflammation (bronchocentric granulomatosis). In the immunocompromised host, Aspergillus may invade blood vessels, causing hemorrhagic infarction (angioinvasive aspergillosis), or it may cause tracheobronchitis, bronchiolitis or pneumonia (airway invasive aspergillosis), as well as abscess formation with or without adjacent tissue invasion. Each of the manifestations of Aspergillus infection has a distinct histologic and high-resolution computed tomography (CT) appearance. This pictorial essay reviews the characteristic high-resolution CT and corresponding pathologic findings of pulmonary complications due to Aspergillus fumigatus.

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.

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.

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.

Aspergillosis (ASM)

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.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.
