Male, 7 years old, history of DNET, yearly follow-up for tumor recurrence. Postoperative findings are again seen related to prior right anterior temporal tumor resection. The surgical cavity cavity is unchanged in size and morphology. Residual T2 hyperintense thickening is again seen posterior to the resection cavity occupying the superior and middle temporal gyri with extension through the temporal stem towards the insula. This tissue shows no significant interval change. No pathologic enhancement is seen within this thickened tissue or anywhere in the vicinity of the resection cavity.Brain parenchymal morphology is otherwise unremarkable. No evidence of new parenchymal signal abnormality, edema or mass effect is seen. No new abnormal fluid collections are detected. The ventricular system is normal in size and morphology.
1.Demonstration of postoperative findings without significant interval change.2.Residual thickened tissue posterior to the resection cavity is stable in size and morphology and free of pathologic enhancement.
