[Hypophyseal apoplexy: clinico-radiologic analysis and clinical course in 18 patients]

The period of time between clinical manifestations and admission of 18 patients with pituitary apoplexy (PA) was of a mean of 6 days with the exception of two cases. Distribution by age and sex, absence of previous endocrinal clinical manifestations in 38.8% of the patients was similar to that of larger series described. Headache constituted an almost constant symptom. The most affected cranial pairs were II (12 patients), III and IV, both in 8 cases. Following decompression surgery, great improvement was observed in visual acuteness in 5 of these patients, and in the ophthalmoplexy in 8. Alterations in the level of consciousness is less and less frequent in the context of PA thanks to the diagnosis of less severe clinical episodes. Similarly, a high rate of clinical suspicion and the use of new imaging techniques (NMR) have contributed notably with the most outstanding findings being resumed. Moreover, a case of PA with associated intracranial aneurysm verified by carotid angiography is described.
