Thoracic canal stenosis resulting from degenerative changes, such as disc herniation, ossification of the posterior longitudinal ligament and ossification of the ligamentum flavum (OLF) is a well-reported clinicopathological entity. However, compression of the spinal cord caused by hypertrophied articular process in the thoracic region is relatively rare compared with compression in the cervical and lumbar regions. The authors report a case of 75-year-old female who developed subacute thoracic myelopathy after minor traumatic event. CT myelogram (CTM) revealed severe thoracic canal stenosis at the T9-11 levels caused by bilateral facet hypertrophy. Laminectomy including medial facetectomy of T9 through T11 was performed and the patient's neurological deficits were resolved except for a slight numbness in the bilateral distal lower extremities. CTM was more useful than myelogram or MRI for discriminating between this disorder and OLF.
