Female, 36 years old, with history of C6-7 disc replacement and worsening left upper extremity pain. Artifact from surgical instrumentation at C6-7 obscures the adjacent vertebral bodies and spinal canal.Alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of edema, replacement or pathologic enhancement is seen. The visualized portions of the cervical spinal cord show normal signal characteristics and are likewise free of pathologic enhancement. No epidural collections are detected.C2-3: No spinal canal stenosis or neuroforaminal narrowing. C3-4: No spinal canal stenosis or neuroforaminal narrowing. C4-5: Minimal disc bulge. No spinal canal or foraminal stenosis. No interval changes. C5-6: The spinal canal is partially obscured by artifact, more so than on the prior exam. No definite foraminal narrowing is seen. C6-7: The spinal canal and parts of the neural foramina are obscured by artifact. The lateralmost aspects of the neural foramina are patent. C7-T1: Minimal central disc protrusion. No spinal canal or foraminal stenosis.
Within the limitations of artifact related to the patient's orthopedic instrumentation, no definite new findings are seen to account for the patient's symptoms.
