Left-sided extra-axial space-occupying lesion in a left parasellar location. It occupies the medial aspect of the left middle cranial fossa and extends 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 shows markedly high T1 and intermediate T2 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 FLAIR fat sat as well as the multiple subarachnoid droplets on the same side as the lesion. No definite enhancement could be noted, although T1 C+ fat sat are not available.
Multiple droplets of fat signal material are scattered in the left subarachnoid space consistent with rupture.
