History of suprasellar lesion for surveillance. Redemonstrated is a large sellar and suprasellar mass measuring 22 x 35 mm (TR x CC), previously 22 x 40 mm. There is interval decrease in T1 signal hyperintensity at the superior aspect of the mass with a minimal residual curvilinear rim. This mass again extends into the left cavernous sinus, surrounding the left carotid artery with superior displacement of the anterior cerebral arteries and optic chiasm. It insinuates itself into the interhemispheric fissure and abuts and displaces the adjacent right frontal lobe including the right gyrus rectus and olfactory trigone. At the right aspect of the mass, there is a small T2 hyperintense, nonenhancing, cystic focus, which may represent trapped fluid versus a true cystic component of the mass. The right A1 segment is located behind the mass. The pituitary stalk is again deviated towards the right. The partially imaged brain demonstrates parenchymal volume loss and a mild degree of periventricular and subcortical punctate T2 hyperintense white matter lesions.
Slight interval decrease in size of the sellar and suprasellar mass with decreased and evolving hemorrhage along its superior aspect.
