Overview
Findings on MRI suggestive of Sheehan's syndrome include decreased sellar volume, empty sella, pituitary remnant tissue or CSF fluid in sella.
MRI
- MRI shows an empty sella, in chronic cases of Sheehan's syndrome.[1][2][3]
- It can also show decreased sellar volume, pituitary remnant tissue or CSF fluid in sella.
- It is done to exclude any pituitary mass.
MRI
- Early
- Enlarged pituitary, with low T1, high T2 homogenous signal
- Ring enhancement
- Late
- Empty sella of normal size.[4]
