Intervertebral disc herniation (IVDH) with nucleus pulposus extrusion, traumatic or not, is a devastating clinical condition accompanied by neurological problems. Here we report a cynomolgus macaque suffering from acute and progressive neurological dysfunction by a blunt trauma due to neck collar, an animal handling device. Tetraplegia, urinary incontinence, decreased proprioception, and imperception of pain were shown on physical and neurological examinations. MRI sagittal T2 weighted sequences revealed an extensive protrusion of disc material between C2 and C3 cervical vertebra, and this protrusion resulted in central stenosis of the spinal cord...

BACKGROUND: Sarcoid involvement of the central nervous system is a rare occurrence, with involvement in approximately 5-10% of all cases. Isolated spinal involvement is an even rarer encounter, only 0.3-1% of all cases. These lesions can form compressive nodules leading to myelopathy. In the presented case of cervical sarcoid, the patient required a decompressive procedure to address cord compression. CASE DESCRIPTION: This is the case of a 39-year-old male presenting with cervical myelopathy caused by a compressive sarcoid nodule who underwent a successful posterior decompressive procedure...

Calcification of the ligamentum flavum (CLF) can cause myelopathy due to spinal cord compression. Only several cases in Caucasian patients have been described. Neurological deterioration can only be stopped by surgical decompression. We report a 63-year-old Caucasian woman presenting with progressive pins-and-needles sensations in both hands, worsened by painful paresthesia in both lower extremities. MRI showed a dorsal compressive mass extending from C2 to Th3 vertebrae with myelopathy at the level of C6. A laminectomy was performed, which improved clinical symptoms...

Morquio's syndrome is associated with systemic skeletal hypoplasia leading to generalized skeletal deformation. The hypoplasia of odontoid process is frequent association, which is responsible for atlantoaxial dislocation causing compressive myelopathy. However, development of sub-axial cervical kyphotic deformity unassociated with odontoid hypoplasia is extremely rare, and coexistence of dorsal kyphotic deformity is not reported in the western literature till date and represents first case. Current case is 16-year-old boy, who presented with severe kyphotic deformity of cervical spine with spastic quadriparesis...

CONTEXT: Spinal arachnoid cysts are usually asymptomatic and discovered incidentally. Expansion of the cyst, whether acute, subacute or chronic, leads to neural compression resulting in radicuopathy and/or myelopathy. FINDINGS: This case report is of a patient who presented primarily with posterior column dysfunction,subacute in onset and rapidly progressing. Images of the cervical spine showed a dorsal arachnoid cyst, causing significant cord compression and signal changes in the cord, with no scalloping of the vertebrae...

STUDY DESIGN: Retrospective study. OBJECTIVES: Few studies have reported a relationship between central motor conduction time (CMCT), which evaluates corticospinal function, and degree of spinal cord compression in patients with myelopathy. Thus, there is no consensus on predicting the degree of prolonged CMCT on the basis of the degree of spinal cord compression. If a correlation exists between CMCT and spinal cord compression, then spinal cord compression may be a useful noninvasive clinical indicator of corticospinal function...

BACKGROUND: Osteochondromas are the most frequent benign bone tumors but only rarely occur along the spinal column and even more rarely induce symptoms from spinal cord compression. CASE DESCRIPTIONS: We report 2 adult patients, both with a history of hereditary multiple exostoses, who presented with cervical myelopathy secondary to osteochondromas. The first patient is a 22-year-old man with numbness and weakness of his right upper limb and neck pain. Radiologic images showed a bony tumor arising from the C3 lamina with evidence of severe spinal cord compression...

BACKGROUND: Atlantoaxial spondyloarthropathy most often results from rheumatoid arthritis, cancer metastasis, or basilar invagination. Dialysis-related spondyloarthropathy is a rare cause of spinal deformity and cervical myelopathy at the atlantoaxial joint. We report 2 patients on long-term hemodialysis who presented with atlantoaxial spondyloarthropathy. CASE DESCRIPTION: Two patients with end-stage renal failure presented with a history of progressively worsening neck pain, motion limitation, and gait disturbance...

PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block...

Patients with intramedullary signal intensity (SI) changes have a poor prognosis after surgical decompression in cervical compressive myelopathy (CCM); however, some patients show no clear relationship between the SI and postsurgical prognosis. This discrepancy may be because no comprehensive and proper quantitative evaluation exists to assess SI on magnetic resonance imaging (MRI). The purpose of this study was prospectively to evaluate the correlation between the clinical features, neurological outcome of patients with CCM, and the quantitative assessment of SI changes preoperatively and postoperatively, and the correlation with SI severity...
