Spastic Quadriparesis

AbstractExpanded endonasal endoscopic approaches provide access to the entire central skull base and craiocervical junction. The authors present a case of an 81-year-old man who presented with progressive spastic quadriparesis to the point of being wheel-chair bound. Cervical spine computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated multilevel extensive spondylitic changes with a large pannus at the C1–2 junction, severely compressing the spinal cord (Figs. 1 and 2). Given the significant anterior spinal cord compression and the patient's substantial weakness, the decision was made to perform an endoscopic endonasal anterior cervical decompression and resection of the pannus followed a posterior cervical fusion. The patient recovered well following surgery with significant improvement of motor function. The preoperative assessment, the step-by-step surgical technique, and the technical nuances are demonstrated and discussed.The link to the video can be found at: https://youtu.be/HzrZO-0Vol4.

Cervical Spine Fusion

Abstract After spontaneous remission of nerve root compression, a myelographic defect may persist. Similarly, myelopathy may remain nonprogressive for long periods despite appreciable myelographic deformity. Although operation may arrest or improve the symptoms of cervical disc lesions and spondylosis, the ultimate confirmation that entrapped neural elements have been relieved permanently can only be provided by postoperative myelography. Preoperative and postoperative myelography documents the significant improvement that can be achieved by using posterolateral and posterior approaches to the cervical spine in patients with nerve root or spinal cord compression. The results in this group of patients were achieved with none of the disadvantages or complications of cervical spine fusion or of the interbody removal of cervical disc tissue, also leading to cervical fusion.

Correct diagnosis of spinal cord disease in childhood is often delayed, resulting in irreversible neurologic deficits. A major reason for this delay is the lack of a reliable means to noninvasively visualize the spinal cord. Magnetic resonance imaging (MRI) should be useful in the evaluation of diseases of the spinal cord. A 1.5 Tesla MRI unit with a surface coil was used to study 41 children, including eight patients with intrinsic spinal cord lesions, eight patients with masses compressing the cord, 12 patients with congenital anomalies of the cord or surrounding bony structures, three patients with syrinxes, and three patients with vertebral body abnormalities. Intrinsic lesions of the cord were well seen in all cases as intrinsic irregularly widened, abnormally intense cord regions. MRI was helpful in following the course of disease in patients with primary spinal cord tumors. Areas of tumor were separable from syrinx cavities. Extrinsic lesions compressing the cord and vertebral body disease were also well visualized. Congenital anomalies of the spinal cord, including tethering and lipomatous tissue, were better seen on MRI than by any other radiographic technique. MRI is an excellent noninvasive "screening" technique for children with suspected spinal cord disease and may be the only study needed in many patients with congenital spinal cord anomalies. It is also an excellent means to diagnose and follow patients with other forms of intra- and extraspinal pathology.

Abstract The relationships between various parameters of tissue damage and subsequent functional recovery after spinal cord injury (SCI) are not well understood. Patients may regain micturition control and walking despite large postinjury medullar cavities. The objective of this study was to establish possible correlations between morphological findings and degree of functional recovery after spinal cord compression at vertebra Th8 in rats. Recovery of motor (Basso, Beattie, Bresnahan, foot-stepping angle, rump-height index, and ladder climbing), sensory (withdrawal latency), and bladder functions was analyzed at 1, 3, 6, 9, and 12 weeks post-SCI. Following perfusion fixation, spinal cord tissue encompassing the injury site was cut in longitudinal frontal sections. Lesion lengths, lesion volumes, and areas of perilesional neural tissue bridges were determined after staining with cresyl violet. The numbers of axons in these bridges were quantified after staining for class III β-tubulin. We found that it was not the area of the spared tissue bridges, which is routinely determined by magnetic resonance imaging (MRI), but the numbers of axons in them that correlated with functional recovery after SCI (Spearman’s ρ > 0.8; p < 0.001). We conclude that prognostic statements based only on MRI measurements should be considered with caution.

Symptoms And Signs

A 35-year-old young man displayed Leber’s optic neuropathy (LHON) due to T14484C and multiple sclerosis (MS) phenotype that was dominated by symptoms and signs of spinal cord impairment. Magnetic resonance imaging (MRI) revealed demyelinating lesions extending from D6 to D11 in the spinal cord with gadolinium enhancement, while only three linear demyelinating lesions were seen on brain MRI. In the literature, a major involvement of the spinal cord was already reported in three of four male patients with the 14484 LHON mutation who developed MS, but the reasons of this peculiar association remain unknown, and further research in this area is needed.

✓ A multilocular extradural cervical spinal hydatid cyst that causes severe spinal cord compression and quadriplegia is relatively rare and difficult to treat. In a patient with this disorder, computerized tomography—guided needle aspiration of the cyst loculations and irrigation using hypertonic saline eliminated the need for emergency surgery and provided complete resolution of the patient's quadriplegia. The subsequent course of the disease was controlled by treatment with albendazole. Magnetic resonance imaging performed 4 months after the procedure demonstrated collapsed cysts and absence of spinal cord compression.

Background: A few young patients were brought in with subacute combined spinal cord degeneration at the Department of Neurology in our hospital. They all have used laughing gas for recreational purposes. Case: A 30-year-old woman, known with alcohol abuse, was presented to our Department of Neurology for having paresthesia and unstable movements of arms, legs, and trunk for 9 days. She has used 50 laughing gas patterns per day. The diagnosis of laughing gas–induced combined spinal cord degeneration was evident by the low count of vitamin B12 combined with lesions shown on magnetic resonance imaging (MRI). Abstaining from the laughing gas, weekly intramuscular injections of hydroxocobalamin and revalidation, she was fully recovered in 8 weeks. Conclusions: Recreational use of laughing gas seems to be more used in our society, however, without having any knowledge of the neurological consequences. The right diagnosis and treatment can provide full recovery in these patients. Furthermore, attention for this diagnosis can help increase social awareness.

The authors present 2 cases involving patients who presented with myelopathy. Magnetic resonance imaging of the cervical spine showed spinal cord signal changes on T2-weighted images without any spinal cord compression. Flexion-extension plain radiographs of the spine showed no instability. Dynamic MR imaging of the cervical spine, however, showed spinal cord compression on extension. Compression of the spinal cord was caused by dynamic anulus bulging and ligamentum flavum buckling. This report emphasizes the need for dynamic MR imaging of the cervical spine for evaluating spinal cord changes on neutral position MR imaging before further workup for other causes such as demyelinating disease.
