<br/><br/> ABSTRACT<br/>This report a case of hemangiopericytoma in an 18-year-old male patient who was referred due to an orbital mass in the right eye. The patient presented with symptoms including blurred vision, proptosis (eye bulging), a pale optic disc, and a relative afferent pupillary defect (RAPD). Orbital computed tomography (CT) ordered by a referring ophthalmologist revealed an intraconal in the right orbit. The patient underwent an excisional biopsy of the orbital mass through a lateral orbitotomy with osteotomy under general anesthesia. Significant hemorrhage was noted intraoperatively.The mass was excised en bloc and sent for histopathological examination, which diagnosed it as a solitary fibrous tumor. Immunohistochemistry revealed hemangiopericytoma with malignant potential. The patient was referred to oncology then radiotherapy for adjuvant external beam radiotherapy using intensity-modulated radiotherapy (IMRT).<br/>
