Figure 5. Magnetic resonance imaging (MRI) of the brain without contrast, 3 years after surgery and proton therapy. (A) Sagittal T1-sequence and (B) Axial T2 fluid-attenuated inversion recovery (FLAIR)-sequence pre-contrast images. Grossly similar postsurgical changes of trans-sphenoidal pituitary resection with T2/FLAIR signal abnormality in the right sellar and parasellar surgical changes within confines of non-contrast (B, blue arrow). Grossly unchanged postsurgical changes within the sella and sphenoid sinus, compared to prior MRIs (Figure 3), although suboptimally evaluated without intravenous contrast exam (A, arrowhead).
