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:Cerebral cysts, usually located in the wall of the caudate nucleus or in the caudothalamic groove. They are found in up to 5.2% of all neonates, using transfontanellar ultrasound in the first days of life.
Comment:In the vast majority of cases, a simple persistence of the germinal matrix is proposed to explain their presence in asymptomatic preterm neonates. Viral infections, mainly with CMV and rubella, are commonly found when the pseudocysts are associated with other abnormalities of the central nervous system. The pseudocysts are then often multilocular.
Synonyms:exact_synonym: Subependymal germinolytic cyst;   Subependymal pseudocyst
