Figure 1 Follow-up axial enhanced T1-weighted magnetic resonance images of a brain metastasis from breast carcinoma treated with stereotactic radiosurgery in a 60-year-old woman. A: Pre stereotactic radiosurgery (SRS) magnetic resonance (MR) image; B: Initial follow-up MR image at 6 wk after SRS demonstrating an initial volume reduction; C: Follow-up MR image at 9 wk after SRS demonstrating a transient volume increase (pseudo-progression); D: Follow-up MR image at 12 wk demonstrating a final volume reduction.

Figure 2 Follow-up axial enhanced T1-weighted magnetic resonance images of a lung carcinoma metastatic to the right cerebellum treated with stereotactic radiosurgery. A: Pre stereotactic radiosurgery (SRS) magnetic resonance (MR) image; B: Initial follow-up MR image at 6 wk after SRS demonstrating an initial volume reduction; C: Follow-up MR image at 9 wk demonstrating volume increase (true-progression); D: Follow-up MR image at 12 wk with final volume increase.
