BACKGROUND AND IMPORTANCE: Solitary fibrous tumor (SFT) has been previously reported for its wide variety of presentations and atypical sites. We report a case of recurrent SFT with multiple intracranial and spinal lesions. CLINICAL PRESENTATION: A 45-year-old female with recurrent right frontoparietal SFT was found to have multiple intracranial and spinal lesions. Most of the lesions are asymptomatic. Each of the intracranial and spinal lesions has been confirmed histologically. In 1999 the patient was found to have a single right temporal SFT and had a gross total resection of the lesion. In 2005 the patient underwent a second gross total resection for the recurrence of the right temporal-parietal lesion, followed by radiation therapy. In 2009 she underwent a third and fourth gross total resection of the right frontoparietal lesion, and the L4-5 mass, as well as a cervical laminectomy for an extramedullary spinal lesion causing spinal compression. CONCLUSION: This is the first case report of recurrent SFT with multiple intracranial and spinal lesions. This case illustrates the nature of recurrence and multiplicity of SFT and raises the importance of a thorough investigation, especially in the entire neuroaxis, in patients with the diagnosis of SFT. This case also questions the justification of the name that was given to this tumor.
