Pituitary apoplexy, therapeutic assessment.
The management of pituitary apoplexy with reference to both diagnosis and operative sequelae remains a major challenge. Acute onset of retro-orbital headache in association with visual loss and ophthalmoplegia are the cardinal symptoms; however, obtundation and signs of subarachnoid hemorrhage also may be present. Good quality plain skull radiographs and complete angiography prove sufficient for preoperative radiographic studies. Preoperative endocrine preparation focuses on supplemental glucocorticoids since these patients must be presumed deficient in cortisol reserve. Residual visual deficit appears to be more a function of the extent of damage at the time of ictus rather than rapidity of decompression. Our experience indicates that transsphenoidal decompression in appropriate cases offers an ideal opportunity to minimize mortality and morbidity. The acute onset of severe retro-orbital headache in association with stupor and ocular palsies would alert most physicians to the potential diagnosis of spontaneous subarachnoid hemorrhage. The association of complex ophthalmoplegias and visual defects in this constellation of symptoms should, in addition, alert one to the possibility of an acute intrasellar or parassellar expansile process. During the past two years, we have had the opportunity to care for 8 such patients with confirmed diagnoses of acute hemorrhagic infarction of the pituitary enabling us to formulate diagnostic and therapeutic schemata with reference to management of this problem.
