Tumor Types

    Benign Lesions

  • Arachnoid Cysts - As the name suggests, Arachnoid cysts are not true tumors but fluid-filled sacs that originate in the middle membrane (arachnoid) of the meninges, the outer cover enveloping the brain and spinal cord.
  • Cranial (Skull) Base Tumors and Lesions

  • Acoustic Neuroma - Acoustic neuromas occur along the eighth cranial nerve that extends from the pons of the brain stem to the inner ear.
  • Cranial Base Tumors - Cranial Base Tumors
  • Meningioma - Meningiomas are the second most common primary tumors affecting the central nervous system.
  • Malignant Tumors

  • Astrocytoma - Astrocytomas can occur anywhere in the brain but are most commonly located in the cerebrum, the largest part of the brain where higher brain functions such as thought and movement are processed.
  • Brain Tumor Locations and Symptoms - Headaches are a common early and continuing symptom of a brain tumor. Patients often describe these as generalized headaches that are worse in the morning and aggravated by such activities as bending, stooping and coughing.
  • Ependymomas - The brain and spinal cord are bathed in cerebrospinal fluid contained within ventricles of the brain and the central canal of the spine; ependymomas grow from ependymal cells that line these structures. Ependymomas make up about six percent of intracranial gliomas and about 60 percent of all newly diagnosed spinal cord tumors.
  • Glioblastoma Multiforme - Comprising 19 percent of all primary brain tumors, glioblastoma multiforme is the highest-grade glioma (Grade IV) and most malignant form of astrocytoma. Glioblastoma multiforme can be diagnosed at nearly any time in life but incidence increases in middle age.
  • Malignant Brain Tumors - Gliomas are malignant tumors that originate in the brain.
  • Metastatic Brain Tumors - Metastatic brain tumors – those that begin elsewhere in the body and move to the brain – are the most common brain tumors.
  • Oligodendrogliomas - Oligodendrogliomas are slow-growing transformations of oligodendrocytes; cells that wrap around axons, the fibers that carry electrochemical signals from neurons. Oligodendrocytes maintain “insulation” that enhances the transmission of signals.
  • Pituitary Tumors and Other Neuroendocrine Tumors

  • Craniopharyngiomas - Craniopharyngiomats are often located above the pituitary gland or next to the pituitary stalk, the structure at the back of the gland that connects to the hypothalamus.
  • Pituitary Tumors - The vast majority of pituitary tumors are benign (non-cancerous), but can be difficult to treat and cause a wide range of serious health problems.
  • Rathkes Cleft Cysts - Rathke’s cleft cysts are benign growths filled with fluid and found in an indentation (Rathke’s cleft) between the pituitary gland’s front and back lobe.
  • Pediatric Tumors

  • Cerebellar Astrocytomas - Cerebellar Astrocytomas are low-grade brain tumors occurring in the cerebellum.
  • Medulloblastomas - Medulloblastomas are a type of “primitive neuroectodermal tumor” (PNET).
  • Pediatric Brain Tumors - Not all brain tumors are alike. In fact, the term “brain tumor” encompasses many types of tumors; these tumors occur in various places in the brain and grow from different types of cells. Tumor characteristics, symptoms, treatment options and outcomes vary greatly.
  • Tumors of the Spine and Spinal Cord

  • Spinal Metastatic Tumors - The spine is the third most common site for metastatic cancer, following lung and liver metastases.  Metastatic tumors are much more common than those that originate in the spine.
  • Spinal Tumors - Meningioma
