HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:A round circumscribed space within a lung that is surrounded by an epithelial or fibrous wall of variable thickness. A cyst usually has a thin and regular wall (less than 2 mm) and contains air, although some may contain fluid.
Comment:The thin wall of cystic lesions differentiates them from cavitary processes, which have thicker and irregular walls and will not be discussed in this article. On chest radiographs, findings of a cyst are often subtle, consisting of lucencies and sometimes linear opacities. An air-fluid level can improve the visibility of a cyst and may suggest infection. For the investigation of cysts, CT is substantially more sensitive than chest radiography, showing a cyst as a ringlike lucency surrounded by a thin wall.
Synonyms:exact_synonym: Lung cyst
