Ossification of the posterior longitudinal ligament (OPLL) is an uncommon cause of compressive myelopathy in the Caucasian population. A case of spastic paraparesis in a Caucasian man whose radiological investigation showed OPLL is presented. The radiographs of the cervical spine showed a strip of bony density posterior to the vertebral bodies, extending from C2 to T1. Computerized tomography (CT) and CT myelography showed OPLL at the same level. Magnetic resonance showed an area of increased signal on T2-weighted sequences at C7-T1 level suggestive of myelomalacia. The patient underwent an open-door laminoplasty (C2 to C7) with improvement of the paraparesis. OPLL should be included in the differential diagnosis of cervical myelopathy. It can be easily detected by plain radiographs and CT of the cervical spine. A review of the clinical and radiological features and the treatment of OPLL is presented.

D013117 Spinal Cord Compression Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions. Clinical manifestations vary with the anatomic site of the lesion and may include localized pain, weakness, sensory loss, incontinence, and impotence.

D015493 Paraparesis, Tropical Spastic A subacute paralytic myeloneuropathy occurring endemically in tropical areas such as the Caribbean, Colombia, India, and Africa, as well as in the southwestern region of Japan; associated with infection by HUMAN T-CELL LEUKEMIA VIRUS I. Clinical manifestations include a slowly progressive spastic weakness of the legs, increased reflexes, Babinski signs, incontinence, and loss of vibratory and position sensation. On pathologic examination inflammatory, demyelination, and necrotic lesions may be found in the spinal cord.
