Accession:MP:0013363 term browser browse the term
Definition:aberrant formation or incomplete differentiation of the pineal gland which normally develops from a saccular outpocketing of the posterior diencephalic roof in the midline of the third ventricle; continued diverticulation and infolding result in a solid parenchymal mass of cords and clusters of pinealocytes and glial-like interstitial cells supported by a meninges-derived connective tissue that carries blood vessels and nerves to the pineal gland
Synonyms:exact_synonym: abnormal conarium development;   abnormal corpus pineale development;   abnormal epiphysis cerebri development;   abnormal glandula pinealis development;   abnormal pineal body development;   abnormal pineal development
