We have read with interest two articles on the natural history of pituitary adenomas related to apoplexy1 and spontaneous infarction.2

It is obvious that they have not considered our published experiences3 on 13 medically and surgically treated patients with classical pituitary apoplexy followed up for up to 9 years.

While striking similarities exist between the two studies, there are, however, some differences in the interpretations and comments between these studies.
In our experience, pituitary apoplexy is a rare disorder in that we encountered it in
