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/.
Term:Continuous diaphragm sign

Accession:HP:0032173 term browser browse the term
Definition:This sign is seen in pneumomediastinum in which air accumulates between the lower border of the heart and the superior part of the diaphragm, which results in complete visualization of the diaphragm in chest X-ray, hence named continuous diaphragm sign.
Comment:Normally, the central part of the diaphragm is obscured by the heart, and hence is not seen on chest radiographs. Though this sign is commonly seen in pneumomediastinum, it can occasionally be also seen in pneumopericardium. This sign when seen, is a differential tool between pneumomediastinum and pneumothorax.
