CHONDROSARCOMA OF THE SKULL BASE
Neuroimaging Clinics of North America, 1994Chondrosarcomas are relatively rare tumors of the skull base. This article surveys the clinical and pathologic features of these lesions. In recent years there have been remarkable advances in both the imaging and treatment of these lesions. Both CT scanning and MR imaging are usually necessary for the complete evaluation of these tumors because of the

Although lipomas are the most common benign tumours of the head and neck, the involvement of the skull base is rare and it is also very rare for a lipoma to undergo osseous metaplasia to become an ossifying lipoma or osteolipoma. We present a case of a solitary osteolipoma involving the skull base in a 17-year-old girl.

Neuroradiology of the Skull Base
Otolaryngologic Clinics of North America, 1984Newer imaging modalities, especially high resolution computed tomographic scanning, have radically altered and expanded the role of radiology in the evaluation and management of lesions affecting the skull base. The location, extent, and tissue characteristics of these lesions can be determined with greater precision than ever before.

Chordomas are rare, benign tumors of the nasopharynx. Because of their location at the skull base, removal of these tumors is usually subtotal. Described is the transcervical-transmandibular approach to the skull base which can be employed in removing these tumors.

The Laryngoscope, 1982
AbstractEarly experience with medium to large tumors of the temporal region has re‐emphasized the value of radiologic preoperative plotting of these space occupying lesions in the sagittal, coronal, and horizontal planes. Attention to probable pathology, neurovascular structures and patient's medical status has been important in determining ...

Ten skull‐base neuromas treated at the Otology Group P.C. are presented. Each case is reported in detail. The method by which preoperative diagnosis was made is reviewed. Specific attention is paid to distinguishing these tumors from chemodectomas. Presenting signs and symptoms are enumerated.

Osteomyelitis of the Skull Base
Neurosurgery, 1992Three cases of osteomyelitis of the skull base with associated problems in diagnosis and therapy are discussed. Patients with atypical skull base osteomyelitis are difficult to diagnose as they have no ear abnormalities, but they often develop multiple cranial nerve deficits mimicking symptoms of a posterior fossa mass.

Journal of the Royal Society of Medicine, 1984
The results are presented of a retrospective study of 7 cases of chordoma affecting the spheno-occipital region and one sited in the upper cervical spine. Follow up data were available on 6 patients. Of these 2 are dead but the rest are alive and well, one of them after more than ten years. The mean survival time of the group so far is 5.2 years.

Skull base osteomyelitis may develop as a complication of paranasal sinusitis or other regional infectious process or as an unfortunate sequelae of iatrogenic injury or trauma. Afflicted patients generally have some form of systemic immunocompromise, most often diabetes, or a history of external beam radiotherapy for a head and neck malignancy with the
