Bartoli Brain Tumor Laboratory
Dr. Jeffrey Bruce, Director of the Bartoli Brain Tumor Research Laboratory, focuses his efforts on three principal areas of brain tumor research: mechanisms of tumorigenesis, novel therapeutic approaches to glial-derived neoplasms, and the immune response to brain tumors. Studies are conducted in...

Skull Base Tumors
Tumors of the skull base were at one time linked to a poor prognosis. Advances in microsurgical techniques, an increased understanding of both the skull base anatomy and behavior of these disease processes, and improvements in neuroimaging have allowed such lesions to be successfully...

Pituitary and Parasellar Tumors
The pituitary gland sits in a bony compartment (called the sella turcica) at the base of the skull and secretes substances, such as growth hormone, prolactin, and adrenocorticotropin hormone, which serve a variety of essential hormonal and metabolic functions. Tumors of the pituitary gland are...

Pineal Region Tumors
The pineal gland, which is a tiny gland located in the back of the base of the brain, creates the neurotransmitters melatonin and serotonin, although its purpose is not entirely clear. Tumors in this region can be of a wide variety of types; the most common are germ cell tumors, which arise from...

Oligodendrogliomas
Oligodendrogliomas are a type of glial cell tumor arising from oligodendrocytes, glial cells that form insulation around neurons, that helps them conduct electrical impulses. These uncommon, usually slow-growing, tumors occur most often in middle-aged patients. Symptoms The symptoms of...

Mixed Gliomas
The brain is comprised of nerve cells as well as other cells that support and protect the nerve cells, called glial cells. Most brain tumors are named after the cells from which they develop. A tumor derived from glial cells is known as a glioma. Astrocytomas, ependymomas and oligodendrogliomas...

Metastatic Brain Tumors
A tumor, or neoplasm, is a mass of abnormal cells that grows at an uncontrolled pace, crowding out and destroying normal tissue. Metastatic brain tumors are malignant growths that are formed by cancer cells originating in a different region or organ in the body. Cancers of the lung, breast, skin, an...

Intraventricular Tumors
Within the brain there are several ventricles, or cavities, that are filled with a clear liquid called cerebrospinal fluid. The cerebrospinal fluid, which also surrounds the brain and spinal cord, helps support and cushion the brain. Tumors in the ventricles are known as intraventricular tumors, and...

Glomus Jugulare Tumors
Glomus jugulare tumors are the most common tumors of the middle ear. Usually slow-growing, they arise from glomus bodies located within the ear. These are very vascular tumors with blood supply from the external carotid artery and internal carotid artery. These tumors are much more common in...
