MRI demonstrated Pituitary mass at the sella continueing to supracella region with intra-tumoral hemorrhage seen on axial MRI T1W and T2WI . The hemorrhagic component is hyperintense on T1-weighted image, heterogeneous on T2-weighted image. Acute cerebral infarction involving Rt ACA teritory showed on axial MRI as hyperintensity on DWI sequence and hypointensity on corresponding ADC map. Rt ICA & ACA signal changes are noted. After contrast administration, Rt ICA is enhance due to partial narrowing and delay passage.
