Germinoma with synchronous involvement of the pineal gland and the suprasellar region: a treatable cause of visual failure in a young adult.

Germinomas constitute 0.1-3.4% of all intracranial tumours and 90% affect patients less than 20 years old. Although they are relatively aggressive tumours, which commonly invade the surrounding tissue and seed within the central nervous system, they are very radiosensitive and carry a favourable prognosis. We describe a 19-year-old man who presented with bilateral visual failure secondary to a germinoma with synchronous involvement of the pineal gland and the suprasellar region. Radiotherapy restored his vision almost back to normal.
