Abstract

Solitary fibrous tumors (SFTs) are uncommon mesenchymal lesions originally described as pleura-based neoplasms. Intradural juxtamedullary SFTs are rare, hard, and scarcely vascularized and generally present a conspicuous extramedullary exophytic component without dural attachment and nerve root involvement. Gross-total resection is the mainstay of treatment, although the absence of an arachnoidal plane and the firm adherence to the spinal cord make resection challenging. We describe the case of a 74-yr-old female patient presenting with a history of progressive spastic tetraparesis due to a cervical juxtamedullary SFT. The patient was not able to walk and magnetic resonance imaging (MRI) of the cervical spine demonstrated a possible intramedullary lesion at C2-C3 with homogeneous enhancement after gadolinium injection. Given the progressive nature of symptoms, the patient elected to have surgical resection of the tumor. The patient underwent C2-C3 laminoplasty and tumor resection under neurophysiologic monitoring. The tumor presented extremely hard without dural attachment or nerve root involvement and was progressively debulked using microsurgical techniques and ultrasonic aspirator. The identification of a plane between the mass and the spinal cord white matter allowed for a gross total resection. Permanent pathological analysis eventually demonstrated SFT. The patient's neurological condition was unchanged postoperatively. MRI performed 2 mo after the operation demonstrated gross total resection of the lesion. At the 6-mo follow-up visit, the patient was able to walk with assistance. The patient signed the Institutional Consent Form to undergo the surgical procedure and to allow the use of her images and videos for any type of medical publications.
