A patient with right temporal radionecrosis was submitted to temporal lobectomy for acute intracranial hypertension developed two years after radiotherapy for a GH-secreting pituitary adenoma. Eight months later, a partial left temporal lobectomy was performed because of further radionecrosis. In both instances the cerebral radionecrosis had the clinical and radiological characteristics of a space-occupying lesion. Bilateral temporal lobectomy was followed by a particular psycho-neurological syndrome with bilateral cortical deafness.
