A 36 years old male was admitted with complaints of headach and disturbance in articulation. Physical findings on admission were as follows: paresis of the right IX, X, XI and XII cranial nerves; narrowing of visual fields; cerebrospinal hypertension up to 400mm H2O. The patient had had irradiation therapy under the diagnosis as reticulum cell sarcoma of the epipharynx prior to the admission. He was biopsied from the epipharynx three times in the admission not to be diagnosed as tumor of the epipharynx.Internal suboccipital decompression was performed as symptomatical treatment. At that time, marked infiltration of the tumor-like mass around the atlas and foramen magnum came into view.In the postoperative course he deteriorated gradually and finally died in spite of hypothermia.Postmortem examination revealed that tumor had its origin at the back side of the epipharynx, and extended up to the posterior part of the base of skull, and distended into the both jugular foramina. The atlas was matted togetherr with tumor mass.The authors discussed about this extension.
