Level localization in the thoracic spine can be problematic. We describe a new method that can be used in difficult cases, e.g., ones where lesions are mid-thoracic, small, or only visible on MRI. Intra-operatively, a midline incision was made and the thoracic spinous processes were exposed. A length of contrast-filled tubing was wound around the processes and the incision was temporarily closed and the patient was transferred to the radiology department for MRI under general anesthetic. Upon return to theatre, the cross sections of contrast-filled tubing and the lesion itself were visible on the MRI scan, allowing localization of the level. This method was accurate and minimized the extent of bone removal required for access. This technique, while not appropriate in every case, is repeatable, and does not require specialized equipment or training. It is an extremely accurate method of localization for difficult cases.
