Optic chiasm position on MR images.
This article describes the results of a study of the distance from the optic chiasm to the tuberculum sellae as seen on sagittal MR images. Measurements revealed an average chiasm-tuberculum distance of 3.8 mm (2.6 mm for females, 4.3 mm for males) and a sizable group in whom the distance was effectively zero. These results show a fairly close correlation with previous anatomic studies. The clo...
متن کاملGiant tuberculum sellae meningioma with unruptured anterior communicating artery aneurysm encased Case report and review of the literature
This 64-year-old man presented with symptoms of optic chiasm and nerve compression from a giant tuberculum sellae meningioma with unruptured anterior communicating artery aneurysm encased. Preoperative magnetic resonance imaging disclosed that the aneurysm was completely enclosed in the tumor, but angiographic studies did not reveal any important arterial narrowing. The embedded aneurysm caused...
متن کاملCase of acute optic nerve compression caused by tuberculum sellae meningioma with optic canal involvement
We present detailed ophthalmic findings in a case of tuberculum sellae meningioma with acute visual symptoms due to optic canal involvement. A 62-year-old Japanese woman reported a 1-week history of headaches and blurred vision in her left eye. Her visual acuity was 0.3 in the left eye with no ophthalmoscopic abnormalities. A relative afferent pupillary defect and inferior temporal field defect...
متن کاملOptic tract edema in a meningioma of the tuberculum sellae.
We report a case of tuberculum sellae meningioma with optic tract edema. Contrary to a prior report on this topic, edema along the optic tract is not only seen in craniopharyngiomas but may be seen (although rarely) in other common parasellar tumors, as in our case of a tuberculum sellae meningioma. The pathogenesis of this edema in meningioma is controversial.
