Home > Conditions > Pituitary Tumors
The pituitary gland is located at the base of the brain. It is a small organ that releases substances which control the basic functions of growth, metabolism and reproduction. Tumors in this area can hinder this function, and large tumors can put pressure on the brain and nerves, causing damage.
Symptoms of Pituitary Tumors:
A pituitary tumor causes symptoms by either causing the pituitary gland to release too much or too little hormones. Symptoms vary depending on the type of pituitary tumor. Generally, patients report symptoms such as:
- Vision changes
- Disrupted menstrual cycles
- Changes in weight
- Hormonal changes
A tumor that secretes hormones produces symptoms by releasing too much of the hormone. While some tumors cause the gland to stop releasing enough hormones. A pituitary tumor may also cause symptoms by growing and pressing on critical structures, like the nerves to the eyes. Most pituitary tumors are benign, though they can be malignant in rare cases. Typically, CT or MRI is needed to diagnose a pituitary tumor.
