MRI scans from a patient who developed representative dissemination recurrence. A Preoperative axial enhanced T1-weighted images and B preoperative sagittal enhanced T1-weighted images showed that the tumor was in the left frontotemporal lobe. C CT images 1 day after operation. D–F Enhanced T1-weighted images follow-up 6 months after resection showed a new in-field lesion and multiple meningeal metastasis (yellow arrows). The blue and red lines represent the isodose lines of PTV, CTV, respectively. MRI Magnetic resonance imaging
