Rosette-forming glioneuronal tumour (RGNT) is a rare central nervous system (CNS) neoplasm that typically arises in the fourth ventricle. It is even more uncommon to arise outside the midline. In this paper, we report two cases of RGNT: one located in the fourth ventricle (a typical site), and the other in the right cerebellar hemisphere (a rare site). Both cases were misdiagnosed on imaging, and the results were inconsistent with the pathological diagnosis. The aim of the article is to deepen medical practitioners' understanding of RGNT by learning from these two cases, summarising cases located in the cerebellar hemispheres and systematically reviewing RGNT.
菊形团形成性胶质神经元肿瘤（RGNT）是一种罕见的中枢神经系统（CNS）肿瘤，通常发生于第四脑室。发生于中线以外的情况更为罕见。在本文中，我们报告了两例RGNT：一例位于第四脑室（典型部位），另一例位于右小脑半球（罕见部位）。两例在影像学上均被误诊，结果与病理诊断不一致。本文的目的是通过学习这两例病例、总结位于小脑半球的病例并系统回顾RGNT，加深医学从业者对RGNT的认识。
