Hybrid Management of Giant Solitary Intracranial Fibrous Tumors: A Report of Two Cases.

Solitary fibrous tumors (SFTs) are rare tumors of vascular origin, derived from pericytes surrounding blood vessels. Their frequency of presentation is mainly in adults, and they can be in various parts of the body, such as the extremities, head, neck, retroperitoneum, and abdomen. These tumors can be either benign or malignant, and their behavior and clinical course are variable, with a significant risk of recurrence and metastasis. We present a two-case report: the first involving a 25-year-old man with right hemiparesis and a history of two prior surgeries at another institution for a diagnosed SFT; the second involving a 48-year-old man with decreased visual acuity and personality changes, with a biopsy confirming SFT. Both cases were managed with embolization followed by resection, with no residual tumor remaining. Treatment of SFTs with embolization and complete surgical resection improves surgical outcomes and reduces the risk of recurrence.
