Left sided extra-axial space occupying lesion with showing left parasellar location. It occupies the medial aspect of the left middle cranial fossa and extending along the lateral aspect of the left cavernous sinus to indent the left frontal lobe and the left gyrus rectus that is mildly displaced towards the right side. The mass showed T1 markedly high and T2 intermediate signals with heterogeneous texture.
The lesion is pushing the M1 segment of left middle cerebral artery posteriorly as well as the A1 segment of the left anterior cerebral artery medially. No intra-sellar extension could be noted.
It has near complete suppression on FAT SAT FLAIR as well as the multiple subarachnoid droplets at the same side of the lesion. No definite enhancement could be noted, although FAT SAT T1 C+ are not available.
Multiple droplets of fat signal material are scattered in the left subarachnoid space consistent with rupture.
