Figure 1. Preoperative T1- weighed MRI with contrast enhancement (A: axial; B: coronal; C: sagittal.). Post operative T1-weighed MRI with contrast enhancement showing resection of the intrasellar portion of the tumor (D: axial; E: coronal; F: sagittal.). Octreoscan images shows lesion (G: axial; H: coronal; I: sagittal.). T1-weighted MRI with contrast enhancement scans 3 months after surgery and Octreotide treatment shows 20% shrinkage of tumor size.
