Solitary fibrous tumor (SFT) generally arises from different soft tissues. It was previously known as hemangiopericytoma. Intracranial SFT is a distinct mesenchymal type of primary brain tumor with an intermediate biological potential. This report described the manifestation and management of a woman (in her late 60 years of age) with a rare extra-axial SFT of cerebellum. SFT has some neuroimaging characteristics that mimic meningioma. We have reported its distinct histopathological findings. Importantly, SFT demonstrates more aggressive local behavior and a significantly higher rate of recurrence than meningioma. In the present case, the skull bone was eroded and eventually penetrated with focal destruction by the tumor. We completely excised the tumor and subsequently reconstructed the skull bone with an artificial alloplastic titanium mesh. This uncommon case report emphasized the value of accurate SFT diagnosis and demonstrated outcomes achieved by complete surgical resection with bony reconstruction.
