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.
Thanx for your efforts,,,,,,,,,but it is so helpful if full history about these cases will be added ,,,,,,,,,,thanx again
