(a)-(d) are MRIs of the sellar region at the age of 18. Coronal T1-weighted image (a), coronal T2-weighted image (b), and coronal contrast-enhanced T1-weighted image (c) show a homogenous lesion in the sellar to suprasellar region. Coronal T2-weighted image after initial TSS (d) confirms GTR of the tumor. (e)-(g) are MRIs of the sellar region at the age of 25. Coronal T1-weighted image (e), coronal T2-weighted image (f), and coronal contrast-enhanced T1-weighted image (g) show a small dumbbell-shaped homogenous lesion on the right side of the sellar region (arrow). GTR: gross total resection; TSS: transsphenoidal surgery.

Brain MRI demonstrated a large mass of approximately 21.5 x 22.9 x 18.1 mm within the sellar to upper sellar regions (Fig. 1a-1c) that was isointense with the gray matter and only weakly enhanced by gadolinium-based contrast.
