Periradicular granulomas and cysts represent two different stages in the development of chronic periradicular pathosis as a normal result of the process of immune reactions that cannot be inhibited.
Aspergillus tracheobronchitis is an uncommon clinical form of invasive aspergillosis with fungal infection limited entirely or predominantly to the tracheobronchial tree. We report a case of Aspergillus fumigatus bronchitis, diagnosed by fiberoptic bronchoscopy, with fungal growth completely occluding the left main bronchus leading to lung collapse and acute respiratory failure in a 60-year-old male with erythroleukemia and profound granulocytopenia.
Aspergillus tracheobronchitis should be considered in immunocompromised patients with suspected lung infection even when the main radiographic finding is atelectasis. Bronchoscopy and histologic examination of identified intraluminal material should be performed as soon as possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
