Abstract

Background: 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.

Case summary: 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.

Conclusion: 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.

与脑室系统无关的小脑上皮瘤：病例报告。

背景：小脑上皮瘤是一种胶质瘤，通常发生在脑室或其附近，靠近上皮。病例摘要：在此，我们报告了一例罕见的完全位于脑实质内的小脑上皮瘤。一名既往健康的 32 岁女性因头晕 1 个月入院。住院期间，脑部磁共振成像显示，右侧小脑半球和小脑下蚓部有一个面积为 57 mm × 41 mm × 51 mm 的占位性病变。患者接受了右侧小脑肿块手术切除。术后病理检查显示为上皮瘤。随访一年，患者情况良好，未见复发：我们进行了文献综述，并总结了关于仅位于脑实质内的小脑上皮瘤的三种理论，这三种理论是诊断小脑实质内上皮瘤的关键。手术和术后放疗是治疗小脑上皮瘤的主要方法。

期刊介绍： The World Journal of Clinical Cases (WJCC) is a high-quality, peer reviewed, open-access journal. The primary task of WJCC is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of clinical cases. In order to promote productive academic communication, the peer review process for the WJCC is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJCC are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in clinical cases.
