Germinoma accounts for more than 50% of neoplasms in the pineal region. It is also known as dysgerminoma or extragonadal seminoma, as opposed to non-seminomatous germ cell tumors (NSGCTs). The latter are more resistant to radiation therapy and require higher doses.
The patient also has a non-enhancing lesion in the right petrous apex, probably a congenital cholesteatoma.
