case_images: MRI brain images. (a) Sagittal and coronal T1 weighted sequence of the sellar region demonstrates a 2.5 cm x 1.5 cm x 1.5 cm heterogeneously T1 hyperintense mass expanding the sella turcica. Note the patchy T1 bright signal throughout the mass, consistent with subacute hemorrhage. (b) Axial T1 sequence of the brain again demonstrates the heterogeneously T1 hyperintense mass (asterisk) extending in to the left greater than right cavernous sinuses (arrow). (c) Coronal T2 sequence shows the T2 hypointense mass (asterisk) with minimal mass effect upon the optic chiasm (curved arrow). (d) Dynamic coronal contrast sequences show the hypoenhancing left sellar mass (asterisk). Note the preserved carotid flow voids within the cavernous sinus (arrowheads). (e) Delayed sagittal contrast sequence shows the hypoenhancing mass (asterisk) with claw-like hyperenhancing pituitary parenchyma along the periphery (arrow).

case_images: MRI of the brain (Figures 1(a)-1(e)) revealed a 2.5 x 1.5 x 1.8 cm mass in the sella turcica consistent with a pituitary macroadenoma with apoplexy.
