Overview
CT scan without contrast is the initial test of choice in emergency department patients who present with sudden-onset severe headache, visual loss, or ophthalmoplegia suggestive of pituitary apoplexy. CT scan can also help to differentiate whether subarachnoid hemorrhage is arising from pituitary hemorrhage or an aneurysm.
CT
CT scan without contrast is the initial test of choice in patients with pituitary apoplexy who present with sudden-onset severe headache, visual loss, or ophthalmoplegia. Pituitary apoplexy on CT presents as a hyper-dense lesion. CT scan can also help to differentiate whether subarachnoid hemorrhage is arising from pituitary hemorrhage or an aneurysm.[1] CT scan may show:
- Intrasellar mass
- Pituitary hemorrhage
