History of pituitary tumor. Evaluate for change. Prior tumor debulking. Again seen is an enhancing pituitary mass with suprasellar extension, which measures up to 22 mm in the craniocaudal dimension, 21 mm in the transverse dimension, and 19 mm in the anteroposterior dimension. These measurements are unchanged since 3/23/2016 allowing for slight differences in measurement technique. There is evidence of gradual enlargement compared to prior studies as noted previously. For example on prior MRI from 1/15/2014, the tumor measures 15 mm in the craniocaudal dimension, 18 mm in the transverse dimension, and 19 mm in the anteroposterior dimension. Again noted is the tumor bulging into the medial aspect of the left cavernous sinus. The tumor also abuts the optic chiasm as before. Unchanged thickening and enhancement along the pituitary stalk. Flow voids of the cavernous internal carotid arteries are maintained.Partially imaged brain again demonstrates small vessel ischemic disease and chronic infarcts in the pons and right inferior cerebellar hemisphere.
Gradual mild increase in size of the pituitary macroadenoma across multiple prior studies as described above although there is no significant change compared to most recent study from 3/23/2016.
