Delayed Cerebral Radiation Necrosis after Neutron Beam Radiation of a Parotid Adenocarcinoma: A Case Report and Review of the Literature
Figure 2
Axial slices of T1 postcontrast (a) and T2 FLAIR (b) MRIs are shown, corresponding to the radiation plan seen in Figure 1. Additional axial T1 postcontrast (c), axial T2 FLAIR (d), coronal T1 postcontrast (e), and sagittal T1 postcontrast (f) slices depict an irregularly enhancing mass lesion in its greatest dimensions, involving the left temporal lobe tip. The lesion measured 4.6 cm in the greatest dimension with significant surrounding edema. There was evidence of temporal bone resection, consistent with prior resection of the left parotid gland.
