Metachronous germinoma after total removal of mature teratoma in the third ventricle: a case report.
نویسندگان
چکیده
A rare case of intraventricular germinoma in the third ventricle, which occurred 30 months after total removal of mature teratoma on the same location in a 29- yr-old man is presented. Recurrence is supposed to represent an acceleration of localized dysplastic processes of totipotent germ cells present in the midline neuraxis or a growth of unidentified microscopic residue of germinoma component in mature teratoma. Although the radiation therapy after total removal of mature teratoma is still controversial, careful follow-up is warranted for evaluating a possible recurrence of other germ cell tumors.

A 21-year-old male presented with a pineal dermoid cyst manifesting as headache and diplopia. He had undergone gross total removal of a pineal mature teratoma 18 years before and had done well until recently. Diffusion-weighted magnetic resonance imaging showed a region of high signal intensity due to a round mass in the pineal region and extending into the trigone of the right lateral ventricl...

Teratomas of the central nervous system are rare and are frequently found in children and young adults. Cystic teratomas found in infancy is a well-recognized but infrequent entity. Intracranial teratomas,like teratomas in general, tend to arise from midline structures such as the pineal gland, but has rarely been found in the third ventricle. We report a rare case of a 6-month-old infant with ...
