If visual field defects or headaches from tumour expansion do occur during pregnancy, a number of therapeutic options are available. Following termination of the pregnancy, either by abortion or delivery of the baby, tumours have become smaller and such symptoms and headaches have resolved in all cases. Thus, if such symptoms occur early in pregnancy, abortion may be indicated. If they occur in the eighth month of pregnancy, premature delivery of the baby may be decided upon, although if field defects and symptoms are minor, careful observation may be all that is required.
