Uncommon tumors of the skull base and uncommon approaches to them

The recognition of a number of uncommon tumors of the skull base is now relatively simple because of three-dimensional computed tomography and magnetic resonance imaging with enhancement. The radiographic classification of these tumors is reviewed, and their treatment is discussed. Although the basic approach to these tumors is the same--radical surgery with decompression of neural and vascular structures--the authors present various operative techniques for gaining access to and removing these tumors. They also examine the role of radiotherapy in supplementing surgical treatment.
