Tumors with epicenter in the thalamus occur in about 4 % of pediatric brain tumors. The histological diagnosis is mainly gliomas. Among them, low-grade glioma (LGG) constituted of a significant entity of the tumors (Cuccia et al., Childs Nerv Syst 13:514–521,
1997; Puget et al., J Neurosurg 106:354–362,
2007; Bernstein et al., J Neurosurg 61:649–656,
1984; Bilginer et al., Childs Nerv Syst 30:1493–1498,
2014). Since Kelly’s report in 1989, >90 % resection of thalamic tumors were achieved in reported series (Ozek and Ture, Childs Nerv Syst 18:450–6,
2002; Villarejo et al., Childs Nerv Syst 10:111–114,
1994; Moshel et al., Neurosurgery 61:66–75,
2007; Albright, J Neurosurg 100(5 Suppl Pediatrics): 468–472,
2004; Kelly, Neurosurgery 25:185–195,
1989; Drake et al., Neurosurgery 29: 27–33,
1991).
