Overview
Pituitary CT scan may be helpful in the diagnosis of growth hormone deficiency if an MRI is not available. Brain CT of pituitary apoplexy is insensitive to the diagnosis of apoplexy unless intracranial hemorrhage is present. Brain CT of adrenal adenoma shows typically has attenuation similar to the brain and calcification is rarely found.
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 is 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 be found.
