Rosette Forming Glioneural Tumor Treated with Conformal Radiation.

Rosette forming glioneural tumors (RGNT) are a rare type of low-grade brain tumor included in 2007 in WHO classification. Given the benign nature of the disease, a complete surgical excision has been considered optimum. However, a handful of cases have reported the locally aggressive nature of RGNT. In addition, radiation may also be considered for a tumor located in areas where surgical excision is difficult. We present a similar case, where surgical risk was weighed against resection and we treated the patient with conformal radiation.
