Recurrent solitary fibrous tumor of the spinal cord: A case report and literature review

Abstract

Solitary fibrous tumor (SFT) is a benign mesenchymal neoplasm occurring anywhere in the body, such as the visceral pleura, while it is extremely rare in the central nervous system, especially within the spinal cord. Here, we present a case of recurrent spinal SFT in a 44-year-old woman who had the tumor resected 5 years before. This time, her magnetic resonance imaging revealed an intradural tumor at the level of C6-7. A secondary resection was performed completely, and the patient's neurological conditions recovered fully after resection. Histological and immunohistochemical findings revealed an SFT. Although rare, the preferred treatment for recurrent tumor in SFT is surgery, and postoperative follow-up is necessary for early detection of tumor progression.
