There are a few reports about surgery of foramen magnum tumors by the anterior approach. We report a case of foramen magnum meningioma who was treated by transoral extirpation and had a good result. A 77-year-old woman was admitted to the Kumamoto University Hospital on June 9th, 1988. 10 year prior to the admission she noticed the numbness in the hands and legs. In 1984 she suffered from pain and dysesthesia in the right chest. In May 1988 she could not walk at all. MRI disclosed an intradural and extramedullary tumor at the level of foramen magnum. The tumor was resected completely by transoral approach and a posterior occipito-C2 fusion by Luque rectangular rod was added. After the operation her pain in the right chest faded away and muscle strength improved gradually. Five months after the operation she is doing standing exercise.
