Patient	Total lesions	Treatment setting	SRS dose	Total lesion failures	Local failure n (location-dose)	Marginal failure n (location-dose)
1	5	Adjuvant	14 Gy (4 lesions); 16 Gy (1 lesion)	2	1 (periventricular lesion- received 14 Gy)	1 (frontal convexity lesion-received 14 Gy)
2	2	Recurrent (prior surgery and RT)	16 Gy (2 lesions)	1	1 (Frontal convexity lesion- received16 Gy)
3	1	Adjuvant	16 Gy (1 lesion)	1		1 (Sphenoid Wing lesion-received 16 Gy)
