A 26-year-old pregnant woman with a fast-growing malignant deep-seated brain glioma was offered a therapeutic abortion to allow subsequent surgical resection. This option was refused by the mother, but the fast tumor growth placed the life of both mo

Background Stereotactic radiosurgery/radiotherapy procedures are known to deliver a very high dose per fraction, and thus, the corresponding peripheral dose could be a limiting factor for the long term surviving patients. The aim of this clinical stu
