Clinical question: Temporal or cerebellar atrophy, pituitary adenoma resection. Signs and symptoms: Nystagmus and memory loss. Pre-and post-enhanced pituitary MRI:The examination demonstrates an enlarged sella with depression of the floor inferiorly. There is a diminutive enhancing tissue within the sella far laterally on the left which a normal size and enhancing pituitary stalk terminates into.There is no evidence of a mass present and findings are consistent with a previously treated adenoma.There are no prior exams for comparison. If such studies are available and provided to the radiology department an addendum to this report is submitted after comparison.Unremarkable bilateral cavernous sinuses, suprasellar visual complex and hypothalamic regions.Pre-and post-enhanced brain MRI:Examination demonstrate a single small focus of cortical T2/flair hyperintensity of the right post central gyrus without detectable abnormal enhancement or susceptibility signal change. The etiology of this finding is not clear however possibility of a small chronic cortical stroke cannot be entirely excluded. Follow up is recommended. If there are prior studies available and provided to radiology department an addendum to this report will be submitted after review.The signal intensity and morphology the brain parenchyma is otherwise entirely within normal on all MRI sequences and without detectable abnormal parenchymal or leptomeningeal enhancement.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.Unremarkable calvarium, soft tissues of the scalp, orbits, paranasal sinuses and mastoid air cells.
1.Pre-and post-enhanced MRI of pituitary demonstrate posttreatment changes of a large pituitary adenoma without residual mass and unremarkable otherwise. Please see above comments.2.Pre-and post-enhanced brain MRI demonstrate a single small focus of cortical T2/flair hyperintensity of the right post central gyrus without enhancement as detailed. Unremarkable exam otherwise. Please see above comments.
