[An autopsy case of pinealoma treated by irradiation about four years ago (author's transl)].

The patient was a thirty years old male, who was diagnosed as having pineal body tumors in June,1969, and treated by irradiation after a ventriculo-atrial shunt operation. He recovered well, and participated in some simple work. In May 1972, he suddenly had convulsions followed by incontinence, and he became nearly apallic. Neuroradiological examinations revealed the presence of left frontal tumor, which was removed, on June 22, 1972. Histological examinations of the tumor proved to be pinealoma of two-cell pattern. Though improved slightly after operation, he became apallic again, developed pneumonia, and died on February 22, 1973.
