Overview
Findings on MRI suggestive of Sheehan's syndrome include decreased sellar volume, empty sella, pituitary remnant tissue or CSF in the sella.
MRI
An MRI can done to diagnose Sheehan's syndrome and to exclude any suspected pituitary mass.The MRI findings in case of Sheehan's syndrome include:
- An empty sella, in chronic cases of Sheehan's syndrome.[1][2][3]
- Decreased sellar volume, pituitary remnant tissue or CSF in sella.
- Early MRI findings
- 'Late MRI findings'
- Empty sella of normal size.[4]
