Abstract：
UNASSIGNED: Solitary fibrous tumor/meningeal hemangiopericytoma (SFT/M-HPC) is a rare neoplasm which accounts for around 1% of the intracranial masses. This pathology has a high risk for recurrence and metastasis to distant locations such as the liver, lungs, and bones. Precise diagnosis necessitates detailed histopathological examination.
UNASSIGNED: We present two case reports of SFT/M-HPC. The first case is a 44-year-old female who presented with headache, nausea, vomiting, and frontal ataxia for several months. Imaging findings showed a large parasagittal extra-axial mass with compression of the frontal horns of both lateral ventricles. She underwent gross total resection with an uncomplicated postoperative period. The patient had no recurrent tumors or distal metastases in the follow-up period of 5 years. The second case is a 48-year-old male who presented with right-sided hemianopsia and hemiparesis. Computed tomography (CT) scans revealed a large parieto-occipital extra-axial mass with superior sagittal sinus engulfment and dislocation of the interhemispheric fissure. He underwent gross total resection with an uncomplicated postoperative period. Six years later, he presented with right-sided weakness. CT scan showed a multifocal recurrent mass at the previous location. He underwent subtotal resection with an uncomplicated postoperative period.
UNASSIGNED: SFT/M-HPC should be considered when presented with a meningioma-like tumor mass on preoperative imaging. Immunohistochemical study is crucial for the correct diagnosis. Strict long-term follow-up examinations and regular magnetic resonance imaging scans are key to preventing the appearance of metastases and large recurrent masses.

摘要：
■孤立性纤维瘤/脑膜血管外皮细胞瘤（SFT/M-HPC）是一种罕见的肿瘤，约占颅内肿块的1％。这种病理有很高的复发和转移到远处的地方，如肝脏的风险，肺,和骨头。精确的诊断需要详细的组织病理学检查。
■我们提供2例SFT/M-HPC病例报告。第一个病例是一名44岁的女性，她出现头痛，恶心,呕吐,额叶共济失调几个月.影像学检查结果显示，矢状旁轴外肿块很大，两个侧脑室的额角受压。她接受了大体全切除术，术后时间简单。在5年的随访期间，患者没有复发的肿瘤或远端转移。第二例是一名48岁的男性，他表现为右侧偏盲和偏瘫。计算机断层扫描（CT）扫描显示巨大的枕骨轴外肿块，上矢状窦吞噬和半球间裂隙脱位。他接受了大体全切除术，术后时间简单。六年后,他表现出右侧的弱点。CT扫描显示先前位置有多灶性复发性肿块。他接受了次全切除术，术后时间简单。
■术前影像学上出现脑膜瘤样肿瘤块时，应考虑SFT/M-HPC。免疫组织化学研究对于正确诊断至关重要。严格的长期随访检查和定期的磁共振成像扫描是防止转移和大的复发肿块出现的关键。
