Contrast-enhanced high-resolution magnetic resonance imaging (MRI) revealed an invasive macroadenoma (21  x  13 mm) with left cavernous sinus involvement (left internal carotid artery encasement) and no evidence of optic chiasm compression (Figures 1(a), 1(b), and 1(c)).
Postcontrast T1 weighted MRI after 1 year of cabergoline treatment: coronal sections at the levels corresponding to Figures 1(a), 1(b), and 1(c); a marked tumor shrinkage was seen (tumor size: 9 x 8 mm).
