Ectopic meningioma anterior to the lacrimal gland fossa.
A 66-year-old man reported a slowly growing tumor on the lateral edge of his left upper eyelid. This lesion was hard but movable on palpation. A neoplasm of the lacrimal gland was suspected. CT showed a highly calcified lesion at the left upper eyelid. Resection of the tumor was performed, which was located just behind the orbital septum and in front of the lacrimal gland. Anatomopathologic investigation of the excised specimen with immunohistochemistry revealed a benign meningioma of a meningotheliomatous type, containing multiple bone elements. An ectopic orbital meningioma is rare, and this is the first case of a unique lateral localization of this lesion. Therefore, it should be included in the differential diagnosis of a lacrimal gland tumor.
