Clinical question: Pituitary lesion. Signs and symptoms: Pituitary lesion, compare to prior exam. Pre and post enhanced pituitary MRI:The examination redemonstrates a masslike lesion with T1 hyperintense, T2 hypointense and without enhancement within the sella and with extension into the basal cistern. There is no evidence of interval change in the signal intensity, size or overall appearance of this lesion since prior study. The lesion within the basal cistern demonstrates subtle mass effect on the suprasellar visual complex without interval change since prior exam. Findings as was noted on prior exam likely represent blood products/hemorrhage. This finding was present on head CT examination from 3-9-14 as a focus of low attenuation in the sella and basal cistern.Cavernous sinuses remain within normal limit normal pattern of enhancement.
Redemonstration of a nonenhancing, T1 hyperintense and T2 hypointense masslike lesion within the sella and basal cistern without any appreciable interval change since prior exam. The finding is suspected of representing trauma and demonstrate very subtle stable mass effect on the suprasellar visual complex.
