Abstract
Intracranial solitary fibrous tumors (SFT) are typically dural based, CD34-positive
neoplasms of mesenchymal origin. Since they were first described in 1996 at the meninges,
fewer than 100 SFT had been reported in both cranial and spinal compartments of the
central nervous system. SFT can resemble other spindle cell tumors both radiologically
and histopathologically, and differentiation can be best achieved through viewing
their ultrastructure and using immunohistochemical techniques. In this report, we
present four patients with SFT. Upon diagnosing two patients with SFT located in the
cerebellopontine angle and parasagittal areas, we reviewed our pathological files
and found two more patients; one having a parasagittal tumor and the other having
a convexity tumor, that had been diagnosed with hemangiopericytoma. These tumours
proved to be SFT after an immunohistochemical re-examination.
