ABSTRACT
The authors analyzed 11 cases of pineal region tumor in young male patients who had been treated at the Capital Armed General Hospital. So, the following results were obtained. 1) Due to the army distinctiveness, all cases were young male patients. 2) An unusual large proportion of pineal region tumor(26.2%) was noted. 3) Headache and vomiting were main presenting symptoms and the duration of symptoms was short. 4) The tumors were mainly presented as a round well-enchancing masses with calcification. Also, nearly all were associated with hydrocephalus. 5) MRI was very useful for the demonstration of tumor extent. 6) Based on the classification of pineal tumor, the tumors of germ cell origin were predominant(81.9%). 7) The extrapineal metastasis was frequent. 8) The tumor marker(alpha-FP and HCG) was postive in 4 cases(36.4%). 9) Germinoma showed excellent prognosis for the irradiation following a drainage procedure.

The Os odontoideum is a developmental anomaly of the axis in which the odontoid process is divided transversely. The Atlanto-axial dislocation due to Os odontoideum is presented. At first, we have performed the posterior atlanto-axial fusion with wire fixation. But the posterior fusion failed in realignment and did not adequately decompress the deformed cord by encroachment on its ventral surface. Next time, we have experienced further improvement following transoral decompression and anterior fusion.
