Female, 52 years old, history of ganglioglioma. Surveillance imaging. A small surgical cavity within the inferior left parietal lobe is stable in size and morphology. Mild T2 hyperintensity within the surrounding parenchyma is also unchanged. Likewise, a small curvilinear region of enhancement along the lateral and superior edge of the cavity is unchanged.No new intracranial lesions are detected. Findings compatible with a Chiari I malformation are redemonstrated similar to prior. Brain parenchymal morphology is otherwise unremarkable. A few very small scattered foci of T2 hyperintensity are seen in the periventricular white matter, a nonspecific finding.No evidence of significant intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles are normal in size and morphology.
A small resection cavity within the left inferior parietal lobe is unchanged in size and morphology. This includes mild enhancement along the cavity margin which may simply represent postoperative granulation.
