A 52-year-old man noticed tension sensation of the shoulder in January, 1962. He complained of the neck pain and occipital headache in March, and then had the symptoms of dyslalia and dysphagia, but no compression symptoms of the spinal cord. He died on the night of 12th Oct, 1962.

The tumor scarcely developed from meninges to medulla, and proliferated to anterior due to the destruction of the atlas.
