A member asked:

How big would a tumor be on the pineal gland before it starts pushing onto the brain stem?

A doctor has provided 1 answer

Brain tumor: Pineal region tumors can be relatively small (1.5 cm) and cause symptoms. Pressure on the tectum of the brain stem will cause compression and narrowing of the aqueduct of Sylvius which causes paralysis of upward gaze and obstructive hydrocephalus. Review the imaging studies with a neurosurgeon to help you understand the problem and the treatment options.
