Diagnostic Considerations

Acute ophthalmoplegia should be considered.

Pituitary apoplexy resulting in internal carotid artery occlusion has been reported due to the mass compressing the bilateral cavernous sinuses, resulting in obliteration of the cavernous portion of the right internal carotid artery. [21]

Isolated postoperative hyponatremia resistant to medical correction consider a central cause, in particular pituitary adenoma and/or apoplexy. [22]

Pituitary apoplexy is rarely associated with subarachnoid bleed and vasospasm, leading to cerebral infarcts and consequent focal neurologic deficits. [23]
