Tentorial solitary fibrous tumour: case report and review of the literature.

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.
