Erosion of the Sphenoid bone

The British Journal of Radiology, 1979
This letter has been prompted by a recent article in the Journal (May 1978) by Witcombe and Cremin describing tuberculous erosion of sphenoid bone. The purpose of this letter is to draw attention to the fact that non-specific inflammatory sinusitis may also cause extensive lytic destruction of the sphenoid bone.

Epithelioid haemangioendothelioma of the sphenoid bone

Journal of Clinical Neuroscience, 2001
The authors report a case of cranial EH occurred in the left sphenoid bone that was totally excised without transfusion. A 26-year-old woman presented with a 1-year history of progressing exophthalmos in the left eye. A cranial X-ray showed a mixed osteolytic and sclerotic expansile mass lesion in the left sphenoid bone.

Radiation-Induced Osteosarcoma of the Sphenoid Bone

Neurosurgery, 1989
Abstract The case of a patient who developed osteosarcoma in the sphenoid bone 15 years after radiation therapy for a craniopharyngioma is reported. Radiation-induced osteosarcoma of the sphenoid bone has not been reported previously. Reported cases of radiation-induced osteosarcomas are reviewed.

Radiology of the sphenoid bone

Clinical Radiology, 1998
The sphenoid bone is located in the central skull base and forms part of the floor of the anterior and middle cranial fossae. The optic foramen, superior orbital fissure, foramen rotundum, foramen ovale and foramen spinosum are found within this complex bone. These formina form important transition zones between intracranial and extracranial structures.

Craniopharyngioma originating in the sphenoid bone

Journal of Neurosurgery, 1972
✓ A case of craniopharyngioma originating in the sphenoid bone is presented. The tumor probably originated in the midline from epithelial cell rests along the path of the involuted craniopharyngeal duct. There was bone invasion and destruction of the floor of the middle fossa with intradural extension of tumor into the left temporal lobe. Survival from

Journal of neuroradiology = Journal de neuroradiologie, 2004
Many operative approaches to the sphenoid are possible. This is due to the anatomical characteristics of this bony structure, close to the facial cavities, covered by a meningeal lining and containing many vascular and nervous components. The choice of operative approach is guided by careful review of imaging data as well as limitations and risks of ...

Giant Cell Tumor of the Sphenoid Bone

Journal of Computer Assisted Tomography, 1983
A case of giant cell tumor of the sphenoid bone is reported, the first case in which a computed tomogram is available. The radiologic features of the neoplasm resembled both pituitary adenoma and parasellar meningioma, but with more bone destruction.

Aneurysmal bone cyst of the sphenoid sinus

British Journal of Neurosurgery, 2001
Aneurysmal bone cysts of the sphenoid sinus are very rare, with only six cases described in the literature. We present a case of an aneurysmal bone cyst of the sphenoid sinus with associated fibrous dysplasia in which the radiological findings had some features of a mucocoele.

Giant Cell Tumors of the Sphenoid Bone

Neurosurgery, 1992
Giant cell tumors of the sphenoid are rare; there are 36 previously reported cases. We report two cases of these tumors in women in their thirties, both associated with pregnancy. In the first patient, the tumor was removed via a transnasal transsphenoidal approach. In the second patient, a Le Fort maxillotomy was required.
