Figure 35: The MRI follow-up controls (T1-w + CM) show an inhomogeneous contrast enhancement of the tumor before therapy. 7 months after SRT, increased size and surrounding edema, centrally reduced contrast enhancement. After 1 year, constant size with again increased contrast enhancement. In the further course, regressing tumor volume. After 4.5 years, again tumor progress (the orange line corresponds to the tumor size at the time of 1st SRT).
