Colloid cyst resection, evaluate for recurrence. Again seen are postsurgical changes related to transcallosal resection of colloid cyst. There is no discernible intraventricular lesion, and the ventricles are unchanged in size. Again seen is extensive patchy cerebral white matter T2 hyperintensity in the periventricular and subcortical white matter, which may represent moderate chronic small vessel ischemic disease. There is mild increase in prominence of the FLAIR signal abnormality in the bilateral frontal lobes, which is favored to represent evolution of the perioperative cytotoxic edema evident on prior MRI from 4/6/2015. No midline shift or herniation. There are postoperative findings related to rhinoplasty.
Slight further evolution of postoperative findings related to colloid cyst resection without evidence of recurrent colloid cyst.
