- Fig 1.
Case 1. Coronal (left) and sagittal (right) gadolinium enhanced T1-weighted MR images on postpartum day 26 show central low signal intensity and peripheral enhancement in the pituitary gland.
- Fig 2.
Case 1. Coronal (left) and sagittal (right) noncontrast T1-weighted MR images 6 months later show marked diminution in the size of the pituitary gland. There is CSF signal intensity in the sella (“empty sella”).
- Fig 3.
Case 2. Coronal (A) and sagittal (B) gadolinium-enhanced T1-weighted MR images on postpartum day 6 show a large low signal intensity sellar lesion with enhancement of the rim. There is extension into the suprasellar cistern, and the lesion abuts but does not compress the optic chiasm.
- Fig 4.
A and B, Case 2. At 5 weeks postpartum, the lesion is markedly smaller and no longer protrudes into the suprasellar cistern (image layout same as Fig 3).
