Overview
Pituitary CT scan may be helpful in the diagnosis of growth hormone deficiency if an MRI is not available.
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]
- No contrast attenuation can vary depending on hemorrhagic, cystic and necrotic components.
- Adenomas typically have attenuation similar to the brain and calcification rarely found.
- CT angiography shows moderate contrast enhancement less marked than one typically sees 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 found.
