Overview
Key CT Scan Findings in Pituitary Adenoma
Macroadenoma
- A solid suprasellar mass that typically has an attenuation similar to brain (30-40 HU) and demonstrates moderate contrast enhancement is highly suggestive of pituitary macroadenoma.
- Calcification and hemorrhage are rarely seen.[1][2]

Microadenoma
- Historically, before the advent of MRI, the pituitary was imaged with CT scan.
- Although CT scan is able to detect up to 80-90% of microadenomas (5-10mm in size), it has less sensitivity to smaller adenomas (less than 5mm in size).[1]
