    The `limited' pneumoencephalogram has been used with excellent success at UCLA for the continuing follow-up of pituitary tumours. It is most useful in following nonsecretory adenomas since tumour regrowth can occur in the absence of clinical signs and symptoms. Total serial pneumoencephalography has not been accepted previously for follow-up of pituitary tumours since there is a significant morbidity. The `limited' pneumoencephalogram of the diseased area drastically reduces the morbidity of the procedure so that the patients are willing to undergo serial studies on an outpatient basis.
