An ependymoma is a glial tumor that usually occurs in or near the ventricle, close to the ependyma. It rarely occurs exclusively in the brain parenchyma without being associated with the ventricle.
Here, we report a rare case of a cerebellar ependymoma completely located in the brain parenchyma. A previously healthy 32-year-old female with a 1-month history of dizziness was admitted to our hospital. During hospitalization, magnetic resonance imaging of the brain revealed a space-occupying lesion measuring 57 mm × 41 mm × 51 mm in the right cerebellar hemisphere and inferior cerebellar vermis. The patient underwent surgical resection for the right cerebellar mass. Postoperative pathological examination revealed an ependymoma. At 1 year follow-up, the patient was doing well and showed no recurrence.
We conducted a literature review and summarized three theories regarding ependymomas located exclusively in the brain parenchyma, which are key to the diagnosis of intraparenchymal cerebellar ependymomas. Surgery and postoperative radiotherapy are the primary treatment options for ependymomas.
室管膜瘤是一种神经胶质瘤，通常发生在脑室或脑室附近，靠近室管膜。它很少仅发生在脑实质内而不与脑室相关。
在此，我们报告一例罕见的完全位于脑实质内的小脑室管膜瘤病例。一名既往健康的32岁女性，有1个月头晕病史，入住我院。住院期间，脑部磁共振成像显示右侧小脑半球和小脑蚓部下有一个大小为57 mm×41 mm×51 mm的占位性病变。患者接受了右侧小脑肿块的手术切除。术后病理检查显示为室管膜瘤。随访1年，患者情况良好，无复发。
我们进行了文献综述，总结了关于仅位于脑实质内的室管膜瘤的三种理论，这对脑实质内小脑室管膜瘤的诊断至关重要。手术和术后放疗是室管膜瘤的主要治疗选择。
