Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

Osteoma

Osteomas are bony growths found most commonly on the skull and mandible; however, they may occur in any bone of the body. Osteomas do not usually cause clinical problems and do not become malignant.

Anderson D, Khalil MK.
Can J Ophthalmol. 1981;16(1):10-5.
Two other patients had large frontal meningiomas causing in one case unilateral pain and swelling of the upper lid plus ptosis and hypotropia, and in the other case bilateral frontal morning headaches and intermittent blurring of vision in one eye; they were thought to have a frontal lobe osteoma and migraine respectively.
