Abstract

Gliosarcoma (GS) is an uncommon central nervous system tumor with several characteristics of a malignant neoplasm and poor prognosis. The majority of GS reports describe a predilection for the cerebral hemispheres, and cases of intraventricular GS are extremely rare, with only a few reported. In addition, intraventricular GS has not been associated with any unique radiographic or clinical features, which can result in misdiagnosis as other intraventricular tumor types. In this report, we present the case of a 32-year-old woman with GS in the trigone of the lateral ventricle and provide a retrospective review of similar, previously reported cases.

摘要

胶质肉瘤（GS）是一种罕见的中枢神经系统肿瘤，具有恶性肿瘤的多种特征且预后较差。大多数关于GS的报告描述其好发于大脑半球，而脑室内GS病例极为罕见，仅有少数报道。此外，脑室内GS与任何独特的影像学或临床特征均无关联，这可能导致误诊为其他类型的脑室内肿瘤。在本报告中，我们介绍了一例32岁女性发生于侧脑室三角区的GS病例，并对既往报道的类似病例进行了回顾性分析。
