(a) Initial: MRI pituitary with and without contrast showing a coronal T1 postcontrast image immediately prior to our patient's pituitary surgery. The red arrow points to a 3 x 3 x 5 mm hypoenhancing focus representing a pituitary microadenoma. (b) Postsurgical: MRI pituitary with and without contrast showing a coronal T1 postcontrast image obtained three months after transsphenoidal pituitary surgery. The red arrow shows that a hypoenhancing focus is no longer seen and has been resected. (c) Postpartum: MRI pituitary with and without contrast showing a coronal T1 postcontrast image obtained four weeks postpartum. The red arrow points to a 3 mm relatively hypoenhancing lesion representing a recurrent pituitary adenoma.

MRI of the pituitary gland revealed a left 4 mm focal lesion (Figure 1(a)). Her postop MRI at that time did not show a definitive adenoma (Figure 1(b)). MRI pituitary illustrated a 3 mm adenoma in the left posterior region of the gland, which was thought to represent a recurrent tumor (Figure 1(c)).
