It is extremely rare for the tumor to originate from the spinal cord. Here, we report a rare case of SFT in the spinal cord that recurred repeatedly and progressed from intramedullary to extramedullary. A 40-year-old man underwent C4-5 intramedullary and extramedullary tumor resection in another hospital. Eighteen years later, he experienced symptoms of myelopathy because of tumor recurrence; therefore, he consulted with our hospital and underwent tumor resection again. During surgery, we found that the tumor had an intramedullary and extramedullary location. Only partial resection was possible because of intraoperative deterioration in the compound motor action potential (CMAP). After resection, the pathological diagnosis was SFT. The postoperative course was good. However, two years later, a third tumor resection was required because of dysuria and tumor growth. In this surgery, total resection of the tumor was possible without intraoperative deterioration of the CMAP. The tumor has not subsequently recurred. However, SFT recurrence is relatively common and careful follow-up is required for early detection of recurrence, even after successful removal of the tumor.}, pages = {217--223}, title = {Recurrence of Solitary Fibrous Tumor of the Cervical Spinal Cord}, volume = {76}, year = {2014} }
