Ependymal cyst of the ovary. A case report.
An unusual morphological variant of a mature cystic teratoma was found at caesarean section in a 23-year-old patient; it appeared as a thin-walled cyst containing clear fluid. Microscopy showed the cyst to be lined by ependyma and the wall to be composed of glial tissue with a small protuberance containing squamous epithelium, adipose tissue and bone.
