Characteristics of the Sphenoid Bone in Crouzon Syndrome

Journal of Craniofacial Surgery, 2021
Background: The goal of this study is to analyze the safety of reconstructive surgeries for Crouzon syndrome, and to understand the deformities and complications related to the surgical procedure. Methods: Thirty-nine subjects underwent preoperative computed tomographic scans were ...

Tuberculous erosion of the sphenoid bone

The British Journal of Radiology, 1978
Sphenoidal erosions due to tuberculosis are reported in four young coloured children. The lytic destruction is emphasized for refence texts indicate that tuberculosis produces a sclerotic reaction when extending to the skull base. Tuberculous osteitis of the skull occurs particularly in coloured children and adolescents.

Capillary hemangioma of the sphenoid bone

Skeletal Radiology, 1984
A capillary hemangioma in the body of the sphenoid bone produced unilateral optic atrophy in a 13-year-old boy. The typical reticulated appearance of an osseous hemangioma was clearly demonstrated only on direct magnification radiographs. At angiography, patchy filling occurred through vessels arising from the internal carotid and internal maxillary ...

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.

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

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.

Aneurysmal Bone Cyst of the Sphenoid in a Child

Annals of Otology, Rhinology & Laryngology, 1982
The aneurysmal bone cyst is a vascular lesion which destroys and expands bone. We report a case of an aneurysmal bone cyst of the sphenoid sinus which resulted in loss of vision due to compression of the optic chiasm. Staged intracranial and extracranial procedures were used to remove the lesion.

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.
