Female, 52 years old, with headaches, history of pituitary lesion, six month follow-up. A heterogeneous, slightly hypoenhancing and perhaps partially cystic/necrotic mass is evident within the right aspect of the sella. The lesion measures up to 19 mm TV, 15 mm CC, and 15 mm AP. Measurements are inclusive of a portion of the lesion which appears to involve the right cavernous sinus. The lesion projects superiorly into the suprasellar cistern and may just contact the optic apparatus. It appears that the native pituitary gland drapes along the left aspect of the tumor. The pituitary stalk likewise deviates to the left of the lesion.The brain demonstrates normal morphology. A few scattered T2 hyperintense lesions are seen in the periventricular white matter, a nonspecific finding. No restricted diffusion is evident. No edema or mass effect is seen. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collections. The ventricles are normal in size and morphology. No pathologic intracranial enhancement is seen.
1.A masslike lesion is evident involving the right aspect of the sella and the right cavernous sinus with slight encroachment on the suprasellar cistern. The lesion is favored to represent a macroadenoma.2.No other significant lesions are evident in the brain.
