Pituitary Adenoma

Pituitary Adenoma

Pituitary adenomas are the fourth most common intracranial tumor after gliomas, meningiomas and schwannomas. A large majority of pituitary adenomas are benign and are relatively slow growing. Adenomas are by far the most common disease affecting the pituitary gland. These tumors most commonly affect people in their 30s or 40s, although they can be diagnosed in children as well. Most of these tumors can be successfully treated. Pituitary tumors can vary in size and behavior. Tumors that produce hormones are called functioning adenomas, while those that do not are called nonfunctioning adenomas.

Craniotomy for Tumor

This procedure, performed under general anesthesia, creates an opening through the skull for brain tumor removal. The surgery usually requires between two to five hours to complete. The length of surgery depends on the type and size of the tumor.

 

Stereotactic Biopsy

In this surgical procedure, the physician takes a small sample of tissue from the brain through a hole in the skull. Stereotactic biopsy is commonly used to take a sample from a tumor. The procedure is usually performed under local anesthesia and requires at least an overnight hospital stay.
