Journal of Postgraduate Medicine. 1997 Apr-Jun; 43(2): 48-9http://imsear.searo.who.int/handle/123456789/117290Sphenoid ridge is the third commonest site of intracranial meningiomas. Although sphenoid ridge meningiomas often involve the optic canal, calcification along the optic nerve has not been reported with these tumors. We describe CT features of a calcified optic nerve in a patient with a calcified sphenoid ridge meningioma.engCalcinosis --etiologyFemaleHumansMeningioma --pathologyMiddle AgedNeoplasm InvasivenessOptic Nerve --pathologySphenoid Bone --pathologyCase Reports
