Pineal Tumors

Pineal Tumors, Symptoms and Causes

Many different tumors can arise near the pineal gland, a gland that helps control sleep and wake cycles. Gliomas are common in this region, as are pineal blastomas.

Benign pineal gland cysts are also seen in this location, which makes the diagnosis difficult between what is malignant and what is benign.
