[Case of pineal body tumor].

A case of epiphyseal tumour diagnosed by means of positive-contrast ventriculography in a male patient is reported. Treatment included ventriculoatriostomy and radiotherapy. In the clinical picture of the disease signs of intracranial hypertension prevailed together with hypothalamic endocrine disturbances, and in view of absent pathognomonic signs of lamina quadrigemina lesion considerable difficulties were encountered and craniopharyngioma was suspected. In the light of the pertinent literature and the present observations the possibility of early diagnosis of epiphyseal tumours based on disturbances of vertical optokinetic nystagmus and changes in auditory tests deserves attention.
