Abstract: | We report a rare case of solitary fibrous tumor (SFT) of the meninges of the posterior fossa presenting as an intracerebellar
hemorrhage. A 29-year-old woman was admitted with sudden-onset severe headache, nausea, and vomiting. A computed tomographic
(CT) scan of the brain revealed an intracerebellar hemorrhage 3.5 cm in diameter. Gadolinium-enhanced magnetic resonance imaging
(MRI) showed a heterogeneous enhancement mass. A posterior craniotomy found a firm, highly vascular tumor attached to the
meninges. Histologically, the tumor showed mostly sclerotic tissues with spindle cells. In few areas, the tumor had a more
compact arrangement of spindle-shaped cells with vascular spaces and highly cellular components. Immunohistochemical study
revealed strong CD-34 immunopositivity in many tumor cells. The tumor was diagnosed as SFT of the meninges. We report the
clinical and histological features of this newly described tumor with a heterogeneous component. |
