Only 3 of these neoplasms have been found to arise in the head and neck region. To our knowledge there are limited reports in the literature of this neoplasm in the cervical spine. A case of biphasic synovial sarcoma of the cervical spine is reviewed. A 29 year-old male presented with pain on the left side of the cervical spine. Physical examination revealed a global loss of cervical motion and large palpable mass in the left paravertebral area. The long-delayed Magnetic Resonance MR scan revealed a soft tissue mass measuring 8.3 centimeters cm X 5.7 cm that was surgically removed. A malignant biphasic synovial sarcoma was diagnosed on pathologic examination. The clinical and imaging findings of an atypically located synovial sarcoma are reviewed. This case report emphasizes the consequences of a limited differential diagnosis prolonged treatment and the failure to perform timely diagnostic imaging in the presence of a paraspinal mass. Background Synovial sarcoma is a seldom encountered aggressive malignant neoplasm of soft tissue that typically arises near large joints of the upper and lower extremities in young adults. Synovial sarcomas account for 7-10 of all soft-tissue sarcomas 1 . The anatomical distribution of synovial sarcomas is well documented with 85 located in the extremities 2 and just 3 located in the head and neck region 3 . Fang et al 4 confirmed the low incidence of synovial sarcoma in the spine in their review of 191 cases and the anatomical distribution of these tumors is seen in Table 1. The designation of the head and neck location is .
