Rathke’s cleft cyst is a rare, benign cyst that appears during early fetal development in the pituitary gland at the base of the brain. The fluid-filled cyst grows from a piece of the Rathke’s pouch, located behind the roof of the mouth. The cyst rarely causes symptoms durin ...

Schwannomas/neurilemmomas are slow-growing, benign tumors that occur on the soft tissue of the nerves from the brain to the spinal cord.  Common symptoms include hearing loss in one ear, and buzzing or ringing in the ear. Dizziness may also occur.  It usually affects middle- ...

Sellar/parasellar tumors grow at the base of the skull near the pituitary gland, where growth hormones are regulated. The growths are usually benign, but can cause headache, double vision and facial numbness if they invade surrounding areas. They may put pressure on the pitu ...

Solitary fibrous tumors are benign, rare growths that frequently form in the lining around the lungs, but can also occur in the head, neck and spinal cord. They are typically diagnosed from ages 40 to 50. Because they grow slowly, these tumors cause no symptoms for many year ...

Subependymoma is a slow-growing, benign brain tumor located near the spinal cord and the ventricles, the fluid-filled areas of the brain. The tumors can obstruct spinal-fluid flow or put pressure on surrounding areas, triggering headaches, nausea, vision, balance problems an ...

A teratoma is a tumor in the brain or spine that grows from a reproductive cell (egg or sperm). It is likely present at birth, having evolved during fetal development, but it is often not diagnosed until ages 11 – 30.  These rare tumors have been known to contain hair, teeth ...

Thyrotropinoma (TSHoma) is a slow-growing, benign tumor in the pituitary gland. These tumors produce too much thyroid-stimulating hormone (TSH), causing the thyroid gland to enlarge and secrete excess thyroxin. This leads to hyperthyroidism, a potentially serious medical con ...

An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein. The connection alters the blood flow so that blood moves directly from an artery into veins, bypassing capillaries that extract nutrients and oxygen and nourish body tissue. AVFs occur mos ...
