✦ Synopsis

In recent years, major advances in the diagno-new enhancing lesions on MRI following treatsis and treatment of patients with brain tumors ment of their tumors with surgery (3 patients), have been seen. Today, evaluation of the central chemotherapy (2 patients), and radiotherapy (2 nervous system almost always includes mag-patients). Two patients underwent resection of netic resonance imaging (MRI). The appearance the lesion revealing gliosis. One patient had seof a new lesion on the MRI scan of a patient rial imaging that showed disappearance of the previously treated for a central nervous system lesions. (CNS) tumor raises concern for recurrent disease This suggests that not all new enhancing lewith the need for selection of new, potentially sions in previously treated brain tumor patients toxic therapy. However, the sensitivity of MRI represent tumor. Histologic proof of a suspicious may allow demonstration of new lesions which lesion should be demonstrated prior to initiation are not due to tumor. We now report three pa-of new therapy. Med.
