Axial T2 and FLAIR images at the level of sella show a solitary ovoid left parasellar well circumscribed lesion with mixed signals, show flow related signals on 3D TOF Noncontrast MR Angiography, as a saccular outpouching from left intra cranial ICA supraclinoid portion is a an Aneurym.
Mixed signals instead of flow void in the outpouching on T2w images may be due to its partial thrombosis.
