Spinal intradural extramedullary tumors account for two thirds of intraspinal neoplasms and are primarily represented by meningioma and schwannoma. 1 Neurilemmoma, or intraosseous schwannoma, typically occurs in the fourth to sixth decade of life and is a rare benign neoplasm that comprises <0.2% of primary bone tumors, with an incidence of 3 to 10 per 100,000 people. 2 The most common axial skeleton site of involvement is the mandible, and rare cases involving the mobile spine have been

neurilemmoma A benign tumour of NEURILEMMA (Schwann cells) that may occur in any peripheral or CRANIAL NERVE or in a nerve of the sympathetic nervous system. Although non-malignant, neurilemmomas of such nerves as the acoustic nerve can be dangerous.
Nussinson E(1), Vigder L, Kaveh Z, Gutman H, Trougouboff P, Tzur N. Author information: (1)Gastroenterology Unit, Central Emek Hospital, Afula, Israel. A case of subserosal gastric neurilemmoma is hereby presented.
Three cases of neurilemmoma—one proved (Case 1) and two additional ones (Cases 2 and 3) with roentgenographic evidence—have been presented. The lesions in Cases 2 and 3 are similar in shape and location, but to date surgical procedures have not been performed in either of the two latter cases.
affect males and females equally. often occurs on flexor surfaces of extremities and head and neck. larger lesions may occur in the pelvis. Pathoanatomy.
Lesion invaginates with pressure. Cutaneous and subcutaneous. Normally, the neurilemmoma is a solitary lesion, and there may be multiple neurofibromas with regard to neurofibromatosis. Generally, a neurilemmoma occurs in an age range of 20 to 50 years of age and may occur in both male and female populations.
