Chondromyxoid Fibroma of the Cervical Spine—a Case Report with a Review of the Literature and a Description of an Operative Approach to the Lower Anterior Cervical Spine
Abstract:A case of chondromyxoid fibroma arising from the C-7 vertebral body and involving the epidural space and paraspinal soft tissues is presented. The surgical treatment of this tumor is described, and the pertinent literature is reviewed.
“…They described a 34-year-old female patient with involvement of the spine with CMF at the T 2 –T 3 level. Additional spinal cases of CMF were reported by Gusdcha [10], Spjut et al [11], Schajowicz and Gallardo [12], Rahimi et al [13], Ramani [14], Torma [15], Dahlin [8], Mayer [16], Merli et al [17], Nunez et al [6], Standefer et al [5]and Schajowicz [18]. Compared to the many hundreds of cases of CMF in the literature involving the skeletal system, Mirra et al [19](in a review of 400 cases of CMF) rightly pointed out that this tumor is rare in the spine.…”

“…In a 1978 review of 6,221 bone tumors, Dahlin [4]considered CMF to represent the ‘least common benign tumor derived from cartilage’ with an incidence of less than 0.5% of bone tumors. Standefer et al [5]also found that CMF constitutes only 0.5% of bone tumors. Nunez et al [6], as well as Dorfman and Cherniak [7], also considered them to be quite rare: ‘less than 1% of primary bone tumors’.…”

“…CMF of the spine is very uncommon, with only 25 cases previously reported in the literature [5, 6, 9, 10, 13, 14, 16, 17, 23, 24, 25, 26, 27, 28, 29, 30]. Of CMF reported in the spine, the thoracic spine is the most common location.…”
Background: We report a case of a 7-year-old white female who presented with acute, progressive bilateral lower extremity weakness over 48 h. Methods: Case report and presentation of clinical, radiological and pathological data on a single case of chondromyxoid fibroma (CMF) of the T2 vertebral body. Results: Magnetic resonance imaging of the thoracic spine revealed an extensive mass invading the lamina of the second thoracic vertebra, causing extensive cord compression and progressive neurological deterioration. Surgical resection and pathologic study of the mass revealed a CMF. Conclusions: A thorough Medline search has revealed that only 25 cases of spinal CMF have been reported, making this lesion an extremely rare bone tumor.

“…Standefer et al [18] use a more classical technique, which involves biclavicular osteotomy combined with sternal splitting. The midline sternal splitting approach is the most extensile procedure, and provides exposure down to T4.…”
The anterior cervicothoracic junction is difficult to expose and many techniques have previously been described. Most of them require an extensile exposure, which can lead to significant morbidity. The aim of this study is to present a less invasive approach, allowing the same exposure on the spine as a larger one. The approach begins with the same incision as the Smith-Robinson technique: a blunt dissection of the posterior face of the manubrium is performed with the finger. An endoscope is inserted through 10-mm trocars, one above the manubrium and the second through the second rib space. The upper mediastinal space is exposed; the dissection is performed on the left side, between the esophagus and trachea medially, between the innominate vein and brachio-cephalic artery distally, and between the left common carotid and internal jugular vein laterally. The recurrent nerve must be protected. Two patients with spine metastases underwent this new approach. A strut graft was fixed anteriorly after decompression of the spinal cord. Levels T1-T3 can be well exposed through this approach, allowing complete vertebral body removal at level T1 or T2. After body removal, the posterior longitudinal ligament is well exposed, allowing complete release of the spinal cord. The use of the endoscope is the key to providing a good view of the spine without an extensile exposure. This new approach is technically feasible. The exposure is sufficient for vertebral body resection and reconstruction by strut graft. The procedure is less aggressive and painful than sternotomy.
“…Standefer et al, 20 reported that the benign radiological appearance of CMF at more common sites may not be entirely analagous to vertebral lesions. Features particular to vertebral CMF include extensive erosion of the bony cortex, even beyond the confines of the periosteum into surrounding soft tissue or spinal canal which may be severe enough to suggest malignant destruction.…”
