History of ADEM most prominently involving her brainstem several months prior, who finished her steroids 3 weeks prior, and 2 weeks after steroid cessation, started having a bad throbbing frontal and all over headache, as well as sensitivity to light/ sound, with nausea and vomiting. There has been interval evolution of postsurgical findings related to right frontal approach stereotactic biopsy of the right pons, with a small focus of susceptibility effect at the biopsy site. There is now only a residual punctate focus of enhancement in the left anterior pons. There are no new lesions. There is no evidence of acute intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits and paranasal sinuses are grossly unremarkable.
