Initial contrast enhanced coronal T1-weighted sequence on MRI showing a large lobulated enhancing solid mass in the sellar and suprasellar regions (white arrows). The mass extends into the subfrontal lobes and in between the two frontal horns causing compression of foramen of Monroe. Inferiorly the mass extends to the sphenoid sinus and into the nasal cavity. The mass appears to encase the cavernous sinus and the optic chiasma.

On baseline MRI, a large lobulated enhancing solid mass was seen in the sellar and suprasellar regions extending into the subfrontal lobes and in between the two frontal horns causing compression of foramen of Monroe (refer Figure 1).
Contrast enhanced axial (a), coronal (b), and sagittal (c) T1-weighted sequence on MRI at 12-month follow-up showing reduction in size of the pituitary macroadenoma following treatment with cabergoline.

There was clinical improvement seen with cessation of CSF leak, marked reduction of serum prolactin (serum prolactin dilutional assay of 14,734 mIU/L at 12 months of treatment), and radiological evidence of tumor shrinkage on MRI (refer Figure 2).
