This is a report of a rare case of pineal metastasis from gastric adenocarcinoma. A 75-year-old male with a previous medical history of subtotal gastrectomy for cancer of the cardia was diagnosed as having hydrocephalus 6 months later. After undergoing a V-P shunt operation, he was transferred to Kyoto First Red Cross Hospital. The patient had neurological abnormalities: bilateral paralysis of upward eye movement, and bilateral sluggish reflex to light. Ten days later the patient suddenly fell into a coma due to intratumoral hemorrhage. The patient soon regained consciousness and received Cobalt-therapy. However he died two months later of pulmonary malfunction due to pulmonary metastasis. An autopsy revealed a pineal tumor metastasized from gastric adenocarcinoma. The tumor involved the body of the pineal gland, and was expanded having a sharply defined margin which extended to the posterior portion of the third ventricle and the bilateral basal ganglia.
