Successful multimodal management of central nervous system solitary fibrous tumor: A case report

Abstract

Solitary fibrous tumors (SFTs) are rare neoplasms that can occur in various locations, including the central nervous system (CNS). We present a case report of a 47-year-old male patient with an intracranial SFT who underwent subtotal resection followed by adjuvant radiotherapy. The patient initially presented with chronic left temporal headache and was diagnosed with an intra-axial double-component mass in the left temporoparietal lobe. Histopathological examination confirmed the diagnosis of SFT, and immunohistochemical staining demonstrated positivity for CD34, Bcl-2, and STAT6. Following the incomplete resection, the patient received adjuvant radiotherapy using volumetric modulated arc therapy (VMAT) technique. During radiotherapy, the patient experienced a spontaneous encephalocele rupture but recovered without complications. One year postradiotherapy, the patient showed no recurrence of symptoms or radiological evidence of tumor recurrence. This case highlights the challenges in the diagnosis and management of CNS SFTs and suggests that subtotal resection followed by adjuvant radiotherapy may be an effective treatment approach in achieving favorable outcomes for these rare neoplasms.
