Abstract：Objective To summarize clinical, imaging and pathological characteristics of the infratentorial rosette-forming glioneuronal tumor for improving the understanding of the disease. Methods Clinical data of 4 patients with surgically and pathologically verified rosette-forming glioneuronal tumor were analyzed retrospectively. The tumors were resected by micro-craniotomy via sub-occipital midline approach. Results Total removal was achieved in 3 patients and nearly total resection in 1. Mutism and ataxia occurred in 1 patient and diplopia in 1. All the patients were followed up for 6 to 24 months, no relapse was observed. The diplopia disappeared but there was no improvement in mutism. Conclusions The rosette-forming glioneuronal tumor is a rare benign tumor. Surgical resection is the most common treatment. Postoperative irradiation or chemotherapy is not recommended but further long-term follow-up is necessary.
