WHO grade 2 ependymoma status post GTR: nystagmus. There are postoperative findings related to posterior fossa tumor resection with minimal residual nonspecific linear enhancement along the posterior aspect of the medulla and medial aspect of the left cerebellar hemisphere, which may be vascular in nature or represent granulation tissue. Otherwise, there is no evidence of gross residual tumor. The edema involving the pons, cerebellum, frontoparietal periventricular white matter, and the basal ganglia appears bilaterally to have subsided, although the sequences are not optimized for evaluating this. There is a left cerebellar developmental venous anomaly. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The orbits, skull, paranasal sinuses, and scalp soft tissues are unchanged.
