Solitary fibrous tumors (SFTs) are rare tumors thought to be of mesenchymal origin. Even though intracranial, especially intraventricular, SFTs are rare, this diagnosis should be considered in the differential for intraventricular lesions. Here, report the case of a female in her 60s who underwent a non-contrast-enhanced magnetic resonance imaging scan of the brain for new-onset memory issues and headache which revealed a well-circumscribed intraventricular lesion in the right lateral ventricle with vasogenic edema, trapping of the temporal horn, and subfalcine herniation. She was admitted and started on dexamethasone prior to surgical treatment of the tumor. A right-sided superior parietal lobule approach was utilized to reach and resect the lesion. Histopathology was consistent with World Health Organization grade I SFT. Only 10 other cases of lateral ventricular SFTs have been reported in the literature. Intraventricular SFT is a rare diagnosis, and, as such, the literature on this topic mostly consists of case reports. Although the lesion is benign, metastases have been reported, and thus, gross total resection remains the standard of care. This case adds to the paucity of SFTs reported in the literature.
孤立性纤维性肿瘤（SFTs）是一种罕见的肿瘤，被认为起源于间叶组织。尽管颅内，尤其是脑室内的SFTs很罕见，但在鉴别脑室内病变时应考虑这一诊断。在此，报告一例60多岁女性病例，该患者因新发记忆问题和头痛接受了脑部非增强磁共振成像扫描，结果显示右侧脑室内有一个边界清晰的病变，伴有血管源性水肿、颞角受压和镰下疝。她入院后在肿瘤手术治疗前开始使用地塞米松。采用右侧顶叶上小叶入路到达并切除病变。组织病理学与世界卫生组织I级SFT一致。文献中仅报道了另外10例侧脑室SFTs病例。脑室内SFT是一种罕见的诊断，因此，关于该主题的文献大多由病例报告组成。尽管该病变是良性的，但已有转移的报道，因此，完整切除仍是标准的治疗方法。本病例增加了文献中报道的SFTs的稀缺性。
