| Popis: | Background and objective There is agreement in the literature that pituitary apoplexy is a rare disorder. As our experience differs from this view, we analysed the incidence in patients operated on for a nonfunctioning pituitary adenoma. Patients and design One hundred ninety-two consecutive patients with a suprasellar, clinically inactive adenoma operated on during the period 1985-1996 were retrospectively reviewed. A diagnosis of pituitary apoplexy was made from relevant neurological symptoms together with pertinent findings at operation. Results Pituitary apoplexy occurred in 41 patients (21%), in 23 patients within 12 days prior to the operation. The male/female ratio was 1.9. Median follow-up time was 13.7 years (range 8.9-19.9). During this period, 12 patients had died, yielding a standard mortality ratio of 1.09 (95% CI 0.62-1.92), similar to that in the patients who had not sustained pituitary apoplexy. Postoperatively, 24% of the patients had normal pituitary function, 38% were panhypopituitary and partial pituitary insufficiency was present in 38%. Subnormal GH secretion was present in virtually all patients tested. Two patients died within 60 days of surgery and in two no or incomplete data were available, although they most likely were panhypopituitary. Conclusion Most of our findings add little to what is known about pituitary apoplexy. On one point, however, they are contrary to previously presented data. We found a much higher incidence of pituitary apoplexy despite rather rigorous criteria for the diagnosis. The outcome as regards survival and endocrine function was not different from that in patients with a nonfunctioning adenoma who did not suffer pituitary apoplexy. |
