Status post recent colloid cyst resection. There are recent postoperative findings related to transcallosal resection of a colloid cyst with a small amount of pneumocephalus and pneumoventricle, as well as mild swelling and diffuse susceptibility effect within the left lateral ventricle choroid plexus. In addition, there is a punctate focus of high T2 signal in the region of the left foramen of Monro with susceptibility effect in this region as well. The ventricles are otherwise unchanged in size. There is patchy T2 hyperintensity and restricted diffusion in the body of the corpus callosum and right cingulate gyrus along the surgical approach that measures up to 18 mm. There is otherwise unchanged mild cerebral white matter T2 hyperintensity, which may represent chronic small vessel ischemic disease. There is no midline shift or herniation. There are postoperative findings related to rhinoplasty. There is hypertrophy of the right inferior turbinate.
Recent postoperative findings related to colloid cyst resection with areas of acute ischemia along the surgical approach and a small amount of hemorrhage within the left lateral ventricle. A punctate focus of high T2 signal in the region of the left foramen of Monro is nonspecific, but may represent hemorrhage and/or a residual portion of the colloid cyst, although superimposed recent postoperative findings serve as confounding factors. Therefore, follow up via MRI would be useful.
