Article Title
Case report of cervical myelopathy due to ossification of the posterior longitudinal ligament in association with flavum ligament ossification: MRI and CT appearance (2013)

Journal Name
Acta Medica Lituanica

1) Bibliography
Boukobza, M., Ušinskienė, J., & Letautienė, S. (2013). Case report of cervical myelopathy due to ossification of the posterior longitudinal ligament in association with flavum ligament ossification: MRI and CT appearance. Acta Medica Lituanica, 20(2). doi:10.6001/actamedica.v20i2.2696

2) Purpose of the Article
The purpose of this article was to analyze the cervical spinal cord damage and spinal canal stenosis due to ossification of the posterior longitudinal ligament (OPLL) which usually affects the cervical spine and leads to progressive myelopathy in 50–60s in Asian population.

3) Brief Description of Procedure and Findings/Results
This article summarizes the radiographic findings of the case study: on lateral plain radiographs of the cervical spine, OPLL appears as a dense strip of ossification of variable thickness. CT features of OPLL include a linear dense strip along the posterior vertebral margin, typically separated from the posterior aspect of the vertebral bodies and intervertebral discs. CT is useful to identify extension of OPLL through the dura, characterized by the “single-layer”, “double-layer” and C-sign. MRI, especially T2-weighted images are most effective to evaluate both degree and extent of the spinal cord and hyperintensities reflecting edema and/or myelomalacia.

4) Conclusions and Comments
The article concludes that for radiological examinations, lateral radiograph of the cervical spine showed intraspinal ossification, CT demonstrated specific dural penetration signs, and MRI disclosed spinal cord compression. Laminectomy was performed and decompression of the spinal cord was confirmed by postoperative MRI.

5) The opinion of the Article
I thought this article was easy to understand. It gave me a better understanding of the case report of cervical myelopathy due to OPLL and flavum ligament ossification based on the CT and MRI images appearance.
