Overview
Pituitary CT scan can be beneficial in the analysis of growth hormone deficiency if an MRI is not available. Brain CT of pituitary apoplexy is insensitive to the analysis of apoplexy until intracranial hemorrhage is present.
CT scan
Pituitary CT scan may be helpful in the diagnosis of growth hormone deficiency if an MRI is not available.
Brain CT findings in pituitary adenoma are:[1]
- Absence of contrast attenuation can differ based on the components present such as hemorrhagic, cystic and necrotic
- Adenomas typically have attenuation similar to the brain and calcification is rarely found.
- CT angiography shows moderate contrast enhancement less marked than in meningiomas.
Brain CT findings in pituitary apoplexy are:[2]
- CT is insensitive to the diagnosis of apoplexy unless intracranial hemorrhage is present.
- The pituitary mass may be evident.
- Fluid levels may be found.
