Abstract The clinical presentations, findings of neuroradiological examinations, laboratory findings, pathological diagnoses, methods of treatment, and results of follow-up of 43 cases of pineal tumor collected at the Nagoya University Hospital from 1958 to 1979 are reviewed. The definitions of calcification of the pineal body and of pineal tumor are given. There is a significant difference in the incidence of calcification of the pineal body between pineal teratomas and pineal germinomas. Although there is a 100\% rate of calcification of the pineal body in cases of pineal germinoma, the rate is very low in cases of pineal teratoma; calcification appears in only a small percentage of the cases of teratoma mixed with germinoma or embryonal carcinoma, or both. In male patients with suprasellar germinoma, there is a high frequency of an associated pineal calcification. No pineal calcification is seen in cases of basal ganglia germinoma. The computed tomographic (CT) findings of pineal teratoma and germinoma are characteristic. CT scanning is superior for early diagnosis of suprasellar and basal ganglia germinomas.
