Recovery of neurological deficit after posterior total en-bloc resection of locally aggressive polyostotic fibrous dysplasia

Summary of background data: A case report of polyostotic and locally aggressive fibrous dysplasia including thoracic spine and rib with the symptom of neurologic deficit. In adulthood Polyostotic fibrous dysplasia which occurs in mature bone and behavior locally aggressive is rarely seen. This is one of the rare cases recoveries of neurological deficit after posterior total en-bloc resection of the huge mass in the thoracic spine presented to date. Methods: The patient was a 49-year-old woman with polyostotic fibrous dysplasia involving the thoracic spine of the sixth vertebral body and rib. Posterior total en-bloc resection in sixth vertebral body and rib and expandable cage placement was carried out to achieve substantial pain relief and stabilization of the spine. Results: The patient's neurological deficit was completely resolved and the pain was significantly reduced. There were no complications associated with the surgical procedure. It was noted that the patient could be mobilized easily after the procedure. No pain or complaints were observed during the twelve-month follow-up. Conclusion: En-bloc resection and 360-degree fusion of spinal column were a good therapeutic option for the reported patient.
