There is a marked male predominance with a M:F of ~13:1. Most patients are 20 years or younger at the time of diagnosis.
See main article: intracranial germ cell tumours.
Treatment and prognosis
Leptomeningeal or intraventricular spread is not uncommon (occurring in 13% 2) at the time of diagnosis. Germinomas are receptive to radiation therapy and survival rates of ~85% are reported 3.
See pineal region mass article.
Pineal region masses
The pineal region is anatomically complex and plays host to a number of unique masses and tumours as well as potentially affected by many entities seen more frequently elsewhere in the brain.
- cystic non-neoplastic lesions
- pineal parenchymal tumours
- germ cell tumours
- tumours also encountered in the pineal region
- pineal gland metastases
- vascular lesions
