As solitary fibrous tumors (SFT) are rare orbital neoplasms, the role of radiotherapy in their management remains unclear. We report three SFT cases who underwent radiotherapy for different clinical scenarios. Case 1 was a 20‐year‐old woman who presented with a 2‐year history of worsening left eye proptosis, eventually leading to its enucleation. A histopathological diagnosis of SFT was established. Recurrence was noted after 3 months and was partially resected, as limited by its location and extent. The residual tumor was given 60 Gy through three‐dimensional conformal radiotherapy. Case 2 was a 23‐year‐old man who had been experiencing painless right eye proptosis for 8 months before undergoing excision, which revealed a diagnosis of SFT. With no residual mass detected on imaging, 54 Gy was delivered to the postoperative bed through intensity‐modulated radiotherapy. Case 3 was a 49‐year‐old man with a 3‐year history of blurred vision and left eye proptosis who underwent subtotal resection, which revealed a diagnosis of malignant SFT. A dose of 64 Gy was delivered to the residual tumor through intensity‐modulated radiotherapy. Grade 2 dermatitis was noted. No worsening in vision was observed. The patients remained recurrence‐free after 18, 12, and 5 months, respectively. Radiotherapy might provide a high tumor control probability in orbital SFT.
