There is a large mass within sellar fossa and suprasellar cistern. The mass causes expansion of the sella and compresses the optic chiasm and floor of 3rd ventricle superiorly. Invasion of the mass to sellar floor and involvement of upper clivus and sphenoidal sinus are also present. The mass is isointense on T1W sequence and slightly hyperintense on T2, FLAIR sequences, enhanced homogenously on post contrast exam. Mild partial encasement of adjacent left ICA is detected.
