PURPOSE OF THE STUDY: @entity439 is an uncommon benign primitive @entity3478 generally observed in young subjects, in a spinal localization in 10% of the cases. We report the clinical, radiological, and therapeutic aspects of seven cases of @entity439 . MATERIAL AND METHODS: This series included seven @entity1 , mean age 11.7 years (range 8-14) who were followed for 9 years on the average (range 2-24 years). Findings were compared with reports in the literature. RESULTS: Four cysts were located in the cervical spine (C1, C3, C4, C7), two in the thoracic spine (T4, T7) and one in the sacrum. Biopsy-resection was performed in six @entity1 . The sacral cyst was treated by selective @entity1416 . Two complications were observed after surgical treatment. Bony filling of the lesion, evaluated by CT scan six months after surgery, was achieved in five cases, incomplete in two without recurrence of cystic cavities. DISCUSSION AND CONCLUSION: @entity80 account for 15% of all primitive @entity5 of the spine. They are more frequent in the cervical and thoracic spine than in a lumbar or sacral localization. One vertebra is involved in most cases, generally the vertebral body and the posterior arch with an asymmetrical extension to one pedicle in some cases. @entity16 of variable severity are frequent and can be improved by surgical @entity5 . CT scan and MRI are the best exams to analyze the spinal cyst, to show bony walls and liquid-liquid levels suggestive of @entity80 , to evaluate the @entity5 extension and to search for @entity1745 . When the CT scan and MRI show characteristic signs of @entity80 of the spine, we do not perform a biopsy systematically if complete @entity5 appears possible. Surgical removal with biopsy is the treatment of choice. Reconstruction and stabilization of the spine must be complete using bone graft with or without instrumentation. In case of medullary involvement, decompression must be performed rapidly with the most @entity5 removal as possible. Selective @entity1416 can be used in some localizations or as preparation to surgery. Radiotherapy is contraindicated in @entity1 because of the risk of radio-induced @entity5 .
