There is a large well-defined suprasellar solid-cystic mass with intrasellar extension. The solid component elicits a low signal on T1, slight high signal on FLAIR and T2 with heterogeneous enhancement on postcontrast sequences. The cystic component shows an isosignal to the cortical grey matter on T1 and very high signal on FLAIR and T2. No restricted diffusion is seen. A mass effect is noted on the optic chiasma which is laminated and displaced superiorly. The floor of the 3rd ventricle is slightly elevated with no ventricular dilatation.
