Skull Base Tumors

Advancing Treatment and Innovation in Patient Care

Many types of skull base tumors and conditions are classified by the type of tumor and its location in the skull base. Certain tumors and conditions tend to occur in specific areas of the skull base. The three main regions of the skull base and the tumors and conditions that occur there most commonly are:

Anterior Cranial Fossa

The anterior compartment of the skull base, which contains the eye sockets and sinuses:

  • Meningioma
  • Olfactory neuroblastoma (esthesioneuroblastoma)
  • Paranasal sinus cancer

Middle Cranial Fossa

The central compartment of the skullbase, which contains the Pituitary Gland. The Pituitary Gland is about the size of a pea and is located in the Sella Turcica (saddle-shaped bony structure in the Sphenoid Bone).

Sellar tumors:

  • Pituitary adenomas
  • Craniopharyngioma
  • Rathke’s cleft cyst

Posterior Cranial Fossa

The posterior cranial fossa is the most posterior aspect of the skull base housing the brainstem and cerebellum.
