A rosette-forming glioneuronal tumor (RGNT) is a rare and slow-growing central nervous system tumor. This tumor is usually assessed by MRI during the follow-up period. RGNT can show alteration of contrast enhancement regardless of tumor growth. Here, we report a case of RGNT arising from pons which shows partial enhancement on initial MRI, smaller enhancement on follow-up MRI at 10 months, and totally disappeared at 18 months without any therapy.
菊形团形成性神经胶质神经元肿瘤（RGNT）是一种罕见的、生长缓慢的中枢神经系统肿瘤。在随访期间，这种肿瘤通常通过磁共振成像（MRI）进行评估。无论肿瘤生长情况如何，RGNT都可表现出对比增强的改变。在此，我们报告一例起源于脑桥的RGNT病例，该病例在初次MRI检查时显示部分强化，在10个月后的随访MRI检查时强化程度变小，且在18个月时未经任何治疗完全消失。
