| ABSTRACT |
|
A rare case of thoracic myelopathy caused by the ossification of hypertrophied ligamentum flavum is presented. A fourty-year old male complained of decreased pain, temperature, touch sense at right lower limb, weak urinary stream, poor penile erection, and constipation. CT revealed an ovoid, homogeneously high density at the site of left T10-11 ligamentum flavum, which compressed the spinal cord posterolaterally. MR imaging showed significant spinal cord compression on the left posterolateral aspect at T10-11 level by a well-defined purely low-intensity signal lesion.
Simple spine X-rays did not show any abnormality. T10 total laminectomy and removal of the ossified ligamentum flavum resolved his neurological dysfunction. Clinical summary of the case is presented and the corresponding literature are reviewed. |
