Thoracic back pain with radiation to the legs. Alignment of the thoracic and lumbar spine is unremarkable. No acute fracture or dislocation is seen. At L5 -- S1 intervertebral level, there is suggestion of an epidural lesion at the central and left central location, causing effacement of the thecal sac and impingement of the left S1 nerve root. This can be seen on series 11, image number 153. It is uncertain whether this represents image artifact, disk extrusion, or other epidural lesions. Further imaging can be obtained with CT myelogram or MRI.The spinal canal and neural foramina at the other levels appear patent.A 12-mm gallstone is noted.
