Abstract:
✓ This study involved 57 patients with benign extramedullary tumors of the foramen magnum (19 neurinomas, 37 meningiomas, and one teratoma), who were operated on between 1957 and 1976. The 37 meningiomas represented 3.2% of 1139 meningiomas of the neuraxis. The initial neurological examinations of about half of these patients were unremarkable. The clinical presentation of tumors of the foramen magnum frequently mimics multiple sclerosis, cervical spondylosis, intramedullary tumor, syrinx, carpal tunnel syndrome, and even normal-pressure hydrocephalus. All operations were performed through a posterior approach, and two surgical deaths (3.5%) were recorded. No surgery for recurrence of tumor was recorded. The follow-up review of 56 patients (98.2%) showed good functional results if the tumor was detected before severe neurological deficits occurred. The possible mechanism of the sensory symptoms and muscle atrophy of the hands is discussed, and the electromyographic findings are reviewed.
