Solitary fibrous tumours (SFT) were first described by Klemperer and Rabin in 1931. They are quite rare in the central nervous system and some histopathological or radiological similarities to meningiomas and haemangiopericytomas can lead to misdiagnoses as these tumours enhance homogeneously in postcontrast images, and even dural tail sign can be demonstrated. To date, only 10 tentorial SFT cases have been reported. In this study, a case of tentorial SFT in a 38-year-old female patient is presented. The patient had a mass lesion located in the left transverse-sigmoid sinus junction with strong contrast enhancement. The surgical treatment enabled gross total removal of a dural-based tumour resembling a meningioma; pathological assessment revealed a solitary fibrous tumour arising from the tentorium. During 47 months of follow-up the patient remained asymptomatic and had no recurrence.
孤立性纤维瘤（SFT）于1931年由克莱姆佩雷尔和拉宾首次描述。它们在中枢神经系统中相当罕见，并且在组织病理学或放射学上与脑膜瘤和血管外皮细胞瘤有一些相似之处，这可能导致误诊，因为这些肿瘤在增强后图像中均匀强化，甚至可以显示硬脑膜尾征。迄今为止，仅报道了10例小脑幕SFT病例。在本研究中，报告了一名38岁女性患者的小脑幕SFT病例。该患者在左横窦-乙状窦交界处有一个肿块病变，增强明显。手术治疗实现了对一个类似脑膜瘤的硬膜下肿瘤的大体全切；病理评估显示为起源于小脑幕的孤立性纤维瘤。在47个月的随访期间，患者无症状且无复发。
