Solitary Fibrous Tumor/Hemangiopericytoma of the Cervical Spine – A Case Report

Abstract Introduction: Due to its rarity, the clinical and radiological characteristics of spinal solitary fibrous tumors/hemangiopericytomas remain largely unknown, with only 68 cases documented worldwide between 2000 and 2017. Case Presentation: We report a case of a 39-year-old female patient who presented to the emergency department with complaints of persisting headaches, a numbing sensation in both arms and a progressive loss of manual dexterity. Physical and neurological examinations were unremarkable. A cervical contrast-enhanced MRI revealed an intradural intramedullary space-occupying lesion at the C3 level, accompanied by extensive edema. The patient underwent a successful cervical laminoplasty under neurophysiological monitoring with en-bloc removal of the mass. She experienced total resolution of her symptoms. Biopsy revealed a grade I solitary fibrous tumor/hemangiopericytoma of the cervical spine, positive for CD34 and STAT6. Ki-67 index was 2%. Conclusion: This case report combines a rare tumor subtype with a unique presentation, and may further advance our understanding of this clinical entity.
