It is suggested that catecholamine secretion may be due to sympathetic stimulation at the level of the diencephalon, by a space-occupying lesion pressing on the thalamohypothalamic pathway. Some of the symptoms of the diencephalic syndrome such as euphoria, irritability, skin pallor, and hypertension may be the result of catecholamine secretion.
