Intracranial solitary fibrous tumor (SFT) is a rare, typically WHO grade I, neoplasm of mesenchymal origin and accounts for less than 1% of all intracranial lesions.1,2 Though SFT is typically benign, it is characterized by frequent local recurrences and the potential for distant spread. In addition, cases with malignant clinical course have been previously reported.3 Gross total resection (GTR) has been correlated with improved survival and is considered the treatment of choice. If complete resection is not feasible, subtotal resection (STR) followed by adjuvant radiotherapy (RT) or stereotactic radiosurgery (SRS) can provide high local control rates.2,4
Sellar region SFT managed with SRS have been rarely reported.5–10 We present a case of a recurrent SFT managed with Gamma-knife radiosurgery and review the English literature to evaluate clinical outcomes and SRS treatment parameters after SRS for sellar SFT.
