Preoperative images demonstrating a large peripherally enhancing, centrally necrotic mass.
Selected images obtained from a scan 24 hours post surgery demonstrating resection cavity and resection of the enhancing mass. No convincing residual enhancing tumor present.
Case Discussion
This patient had a histologically proven glioblastoma.
These images are merely to indicate the importance of having pre-and post-contrast T1 images in the postoperative setting, to allow assessment for any residual tumor.
Note: IDH mutation status is not provided in this case and according to the current (2016) WHO classification of CNS tumors, this tumor would, therefore, be designated as a glioblastoma NOS.
