[An unusual manifestation of a pineal tumour (author's transl)].

In the last two years, out of 186 cases of brain tumours we have treated 10 tumours in the pineal region. One of these patients had a pineocytoma. The patient was admitted to our clinic with generalized epilepsy. At the time of admission there were no neurological deficits. In the CT scan we found a tumour in the pineal region with cystic extension in the right temporo-occipital region. The tumour was totally excised and the patient did well postoperatively. The only neurological sequela was a left-sided homonymous hemianopia. He resumed his former profession and is working successfully up till now. It was necessary to radiate the patient, as no tumour recurrence was demonstrated in the CT scan.
