case_images: Pre- and post-operative day 1 computed tomography scans. The postoperative scan was acquired shortly after the patient developed a depressed neurologic status and focal neurologic deficit and minutes after mannitol had been started. Postoperative changes, but no focal mass lesions or postoperative complications were seen on the final read. Of note, the brain appears full both pre-and postoperatively.

case_images: The decision was made to administer hyperosmolar therapy and obtain a CT due to the concern for a new mass lesion, such as postoperative hematoma causing her acute decline in GCS and a focal neurologic deficit. 25 g of mannitol was given at 15 h postoperatively, and her imaging was obtained shortly after [Figure 1].
case_images: Post contrast pre- and postoperative day 2 magnetic resonance imaging scans. Of note is a gross total resection with expected postoperative changes and no evidence of a lesion that would have explained a focal cranial nerve deficit.

case_images: Postoperative MRI acquired on postoperative day 2 showed gross total resection of the mass with expected postoperative changes [Figure 2], with no lesions that would have explained the unilateral pupillary findings.
