Abstract：
BACKGROUND: Solitary fibrous tumor (SFT) is an infrequent spindle cell tumor derived from mesenchymal tissue, which can manifest in diverse anatomical locations, primarily in the pleural cavity and infrequently in the central nervous system. SFT is predominantly observed in individuals aged between 40 and 50 years old, with a slightly higher occurrence in males than in females.
METHODS: This case report describes a female, age 15, who had migraines for 2 months prior to the diagnosis of an intracranial tumor. Computed tomography and magnetic resonance imaging showed a mass located in the right parietooccipital region with surrounding edema and a compressed right lateral ventricle. Neurosurgery was utilized to successfully remove the mass, and single intracranial fibrous tumor (grade I) was identified by postoperative pathological analysis. During an 8-month follow-up period, the patient did not experience any recurrences.
CONCLUSIONS: SFT is often misdiagnosed as meningioma because of their similar imaging characteristics. However, identifying the distinctive features of SFT on magnetic resonance imaging can distinguish it from meningioma and help to select appropriate treatment. The complete preoperative imaging data for this case indicated a highly vascularized tumor. Preoperative vascular embolization treatment reduced any difficulties during the subsequent tumor resection and minimized intraoperative bleeding.

摘要：
背景：孤立性纤维性肿瘤（SFT）是一种罕见的源自间充质组织的梭形细胞肿瘤，可以表现在不同的解剖位置，主要在胸膜腔中，很少在中枢神经系统中。SFT主要在40至50岁之间的个体中观察到，男性的发生率略高于女性。
方法：本病例报告描述了一名女性，年龄15岁，在诊断为颅内肿瘤之前有2个月的偏头痛。计算机断层扫描和磁共振成像显示位于右顶枕区域的肿块，周围水肿和右侧脑室受压。神经外科手术被成功地切除了肿块，术后病理分析发现单个颅内纤维瘤（I级）。在8个月的随访期间，患者未出现任何复发.
结论：SFT由于其相似的影像学特征，常被误诊为脑膜瘤。然而,在磁共振成像上识别SFT的独特特征可以将其与脑膜瘤区分开来，并有助于选择合适的治疗方法。此病例的完整术前影像学数据表明高度血管化的肿瘤。术前血管栓塞治疗减少了随后肿瘤切除期间的任何困难，并最大程度地减少了术中出血。
