Overview

Findings on MRI suggestive of Sheehan's syndrome are 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 are:[1][2]

  • Early MRI findings:
    • Enlarged pituitary, with low T1, high T2 homogenous signal may be seen.
    • Ring enhancement is observed.
  • Late MRI findings:
