Patient Data

Age: 60 years
Gender: Female

A large well marginated mass in the sellar region extends into the suprasellar region. Slightly heterogenous but intense enhancement following IV contrast administration confirms the presence of a mass. Imaging appearances are highly suggestive of a pituitary macroadenoma.

The heterogenous T2 signal is likely to be due to internal hemorrhage.

Restricted diffusion is seen on diffusion weighted imaging. This is important as it has been reported as an early sign of pituitary apoplexy 1.

Case Discussion

Histology following resection demonstrated a pituitary adenoma.
