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:Dural tail sign

Accession:HP:0032268 term browser browse the term
Definition:This sign represents thickening and enhancement of the dura mater in continuity with a mass, which on MR images, gives the appearance of a tail arising from the mass. The dural tail is thought to represent reactive change; however, it may also be due to tumor invasion. Three criteria need to be met for a positive dural tail sign: the tail should be seen on two successive images through the tumor, it should taper away from the tumor, and it must enhance more than the tumor.
Comment:This sign has been traditionally considered as highly specific for meningioma. However, it is seen only in 60% of meningiomas and has also been reported in nonmeningiomatous lesions such as chloromas, primary CNS lymphomas, sarcoidosis, schwannomas, metastases, and syphilitic gummata.
