CT demonstration of cervical spinal cord compression--cause of reversible itching and burning in the lower extremities.

Cervical spinal cord compression is easily and accurately demonstrated by CT. Isolated atypical sensory symptoms in the saddle area and lower extremities may be the earliest and only manifestations of cervical spinal cord compression from cervical spondylosis. A case is presented manifesting such symptoms, which were reversed completely by surgical decompression of the cervical spine.

Epidural spinal cord compression in cancer patients: diagnosis and management.

In most patients with spinal cord compression due to epidural metastasis, the initial symptom is progressive back pain with an axial or radicular distribution, but early symptoms are often nonspecific. Since the key prognostic factor is the neurologic status at the time of presentation, and since early complaints are often nonspecific, a high index of suspicion is needed to diagnose this complication early.

Escalation of radiation dose beyond 30 Gy in 10 fractions for metastatic spinal cord compression.

PURPOSE: In many centers worldwide, radiotherapy for metastatic spinal cord compression (MSCC) is performed with 30 Gy in 10 fractions. This study investigated the potential benefit of dose escalation. METHODS AND MATERIALS: Data from 922 patients with carcinomas causing MSCC were retrospectively evaluated. The outcome of 345 patients treated with 10 fractions of 3 Gy in 2 weeks was compared with the outcomes of 577 patients treated with 37.5 Gy in 15 fractions within 3 weeks or 40 Gy in 20 fractions within 4 weeks. Additionally, 10 potential prognostic factors were investigated: age, gender, performance status, tumor type, interval between cancer diagnosis and MSCC, number of involved vertebrae, other bone and visceral metastases, ambulatory status, and the interval to the development of motor deficits before radiotherapy. RESULTS: Motor function improved in 19% of patients after 30 Gy in 10 fractions and in 22% after greater doses (p = 0.31). The local control (p = 0.28) and survival (p = 0.85) rates were not significantly different with doses >30 Gy. Better functional outcome was associated with the absence of visceral metastases, an interval between tumor diagnosis and MSCC of >12 months, ambulatory status, and an interval to the development of motor deficits of >7 days. Improved local control was significantly associated with no visceral metastases, improved survival with favorable histologic features (breast or prostate cancer), no visceral metastases, ambulatory status, an interval between cancer diagnosis and MSCC of >12 months, and an interval to the development of motor deficits of >7days. CONCLUSION: Escalation of the radiation dose to >30 Gy in 10 fractions did not improve the outcomes in terms of motor function, local control, or survival but did increase the treatment time for these frequently debilitated patients. Therefore, doses >30 Gy in 10 fractions are not recommended.

Neurogenic bladder dysfunction in patients with neoplastic spinal cord compression: adaptation of the bladder management strategy to the underlying disease.

OBJECTIVES: To study the outcome of different bladder management strategies in patients with neoplastic spinal cord compression. METHODS: 22 patients with neoplastic spinal cord compression underwent urodynamic examination. According to the urodynamic data and the underlying disease different bladder management strategies were recommended. In patients with curatively treated disease a full bladder rehabilitation program was arranged. In patients with metastatic malignant disease, voluntary voiding was continued if possible or a suprapubic catheter was placed. RESULTS: Eight patients were treated with curative intention. Of those, 2 patients were able to void during urodynamics continued normal voluntary voiding. Six patients were taught intermittent catheterisation, with three additionally received oral anticholinergic treatment because of UMN lesion. At follow-up, all patients had successfully finished bladder rehabilitation program and at follow up, all patients were continuing their previously recommended bladder rehabilitation program. Fourteen patients had malignant disease and were treated palliatively. In 2 patients with UMN lesion, voluntary control of micturition was maintained and both continued voluntary voiding. In 12 patients a suprapubic catheter was inserted. At follow-up, 9 out of 14 had died (mean 8 month after primary visit), the remaining 5 continued treatment with suprapubic catheters. CONCLUSION: Underlying disease and life expectancy should be considered for the selection of bladder management in patients with neoplastic spinal cord compression. In patients with curatively treated disease, a full bladder rehabilitation program is recommended while in patients with malignant disease and palliative care, a suprapubic catheter might be the treatment of choice.

Synovial cyst of dens causing spinal cord compression. Case report.

We report a rare case of synovial cyst of the dens (odontoid process) in a 61 year old women with no previous history of trauma. She had progressive symptoms of 1 year's duration due to spinal cord compression. Magnetic resonance imaging of cervical spine revealed a large mass posterior to the dens which was compressing the spinal cord near the cervicomedullary junction. This lesion was at first considered radiologically to represent an exuberant pannus formation or a meningioma of the foramen magnum, but subsequent surgical intervention and pathological examination revealed that it was a synovial cyst. Similar cases reported in the literature are reviewed and discussed.

A population-based study of malignant spinal cord compression in Ontario.

DESIGN: Population-based cohort study. BACKGROUND: Malignant spinal cord compression (MSCC) has long been recognized as an important complication of cancer, but its incidence is unknown. OBJECTIVES: To describe the incidence, the management, and the outcome of MSCC in the cancer population of the Canadian province of Ontario. METHODS: Episodes of MSCC, and treatments used for each episode, were identified by linking electronic hospital separation records and cancer centre records to Ontario's population-based cancer registry. The cumulative frequency of MSCC in the last 5 years of life was described in the 121435 patients who died of cancer in Ontario between 1990 and 1995. Survival after the first episode of MSCC, and duration of hospitalization with MSCC, was described. RESULTS: The cumulative probability of experiencing at least one episode of MSCC in the 5 years preceding death from cancer was 2.5% overall, and ranged from 0.2% in cancer of the pancreas to 7.9% in myeloma. Overall, 60.2% of first episodes of MSCC were treated with primary radiotherapy, and 16.1% with surgery +/- postoperative radiotherapy, while in the remaining 23.7%, there was no record of radiotherapy or surgery. Overall, the median survival following the first episode of MSCC was 2.9 months. The diagnosis of MSCC was associated with a doubling of the time spent in hospital in the last year of life. CONCLUSION: MSCC is a fairly common occurrence among patients dying of cancer. There is a 40-fold variation in the cumulative incidence of MSCC among different types of cancer.

Metastatic paraganglioma causing spinal cord compression.

We describe two cases of metastatic retroperitoneal paraganglioma associated with extradural spinal cord compression. Both occurred in young men; one being metastatic at presentation, the other becoming metastatic 19 years after attempted surgical resection. Despite a long, relatively stable natural history after diagnosis (10 and 19 years, respectively) both had an acceleration of their disease once extradural disease was detected. These cases illustrate the potentially aggressive nature of this disease, the need for long-term follow-up and the effectiveness of a variety of therapies for palliation, and also raise the possibility of "prophylactic" treatment to prevent spinal cord compression.

Changes in synapses and axons demonstrated by synaptophysin immunohistochemistry following spinal cord compression trauma in the rat and mouse.

OBJECTIVE AND METHODS: To evaluate synaptic changes using synaptophysin immunohistochemstry in rat and mouse, which spinal cords were subjected to graded compression trauma at the level of Th8-9. RESULTS: Normal animals showed numerous fine dots of synaptophysin immunoreactivity in the gray matter. An increase in synaptophysin immunoreactivity was observed in the neuropil and synapses at the surface of motor neurons of the anterior horns in the Th8-9 segments lost immunoreactivity at 4-hour point after trauma. The immunoreactive synapses reappeared around motor neurons at 9-day point. Unexpected accumulation of synaptophysin immunoreactivity occurred in injured axons of the white matter of the compressed spinal cord. CONCLUSION: Synaptic changes were important components of secondary injuries in spinal cord trauma. Loss of synapses on motor neurons may be one of the factors causing motor dysfunction of hind limbs and formation of new synapses may play an important role in recovery of motor function. Synaptophysin immunohistochemistry is also a good tool for studies of axonal swellings in spinal cord injuries.

[Cytology of the cerebrospinal fluid in dogs with brain tumors and spinal cord compression. Part 4].

The results of cerebrospinal fluid (CSF) cytology of 9 dogs with brain tumors and 50 dogs with spinal cord compression are discussed. Of the 50 dogs with spinal cord compression, disc protrusion was diagnosed in 31, myelomalacia in 7, discospondylitis in 3 and spinal cord tumors in 9 dogs. In 4 of 9 dogs with brain tumors, tumor cells could be found by the sedimentation apparatus of Kölmel. Pleocytosis existed in 6 patients. In about 70% (29 of 41) of cases with disc protrusion, more than 200 cells could be evaluated in the CSF sediment, consisting mostly of transformed lymphocytes and activated monocytes. As the neurologic deficits increased, the amount of cells and especially cell complexes increased. This was especially evident in cases with myelomalacia of the spinal cord. Only in cases with discospondylitis or spinal cord neoplasia was the CSF cytology unchanged.

Spinal cord compression by heterotopic ossification associated with pseudohypoparathyroidism.

This report describes a 37-year-old man presenting with a gait disturbance due to spastic paraparesis. Physical findings showed typical features of Albright's hereditary osteodystrophy, including short stature, obesity, brachydactyly and dental hypoplasia. He was diagnosed as having pseudohypoparathyroidism type Ia, on the basis of his hypocalcaemia, hyperphosphataemia, increased plasma level of parathyroid hormone (PTH), and the unresponsiveness to exogenous PTH loading of his urinary excretion of both nephrogenous cyclic adenosine monophosphate and phosphate. Magnetic resonance imaging and myelographic computed tomographic scans clearly demonstrated severe compression of the spinal cord at T 9/10 by tumour-like ossifications of the paravertebral ligaments. Neurosurgical decompression therapy was, therefore, performed to alleviate his spastic paraparesis. This was a rare case of pseudohypoparathyroidism complicated with spinal cord compression caused by ectopic ossification of the ligaments.

Adverse effects of the management of malignant spinal cord compression.

As a prelude to further work which attempts to improve the management of metastatic spinal cord compression the efficacy and adverse effects of existing therapy has been assessed. All papers dealing with the management of malignant spinal cord compression since 1960 have been reviewed. Data from this review is presented in a novel manner in order to identify not only the degree of successful return to ambulation achieved but more importantly the extent of the adverse effects which occur during existing management. It is seen that, while in general some 35% of patients treated in any manner retain or return to the ability to walk, some 20% to 25% sustain major neurological deterioration. In addition, those patients treated by laminectomy who do deteriorate may be subject to a significant rate of perioperative mortality and major structural complications related to the surgical wounds. In the light of the adverse factors described, the role of laminectomy as first-line management of malignant cord compression is questioned. Alternative modes of treatment are discussed and a tentative scheme of management described which it is hoped will lead to a better quality of survival of the group as a whole in addition to maintaining, or perhaps, improving the rate of successful return to ambulation.

Epidural spinal cord compression from metastatic tumor: results with a new treatment protocol.

Eighty-three patients with epidural spinal cord compression, from metastatic cancer were treated with high-dose adrenocorticosteroids and a new radiation fractionation protocol. Only those patients were included who had complete or almost complete block on myelography and who had not received prior radiation therapy to the area of compression. Patients were given 100 mg of dexamethasone intravenously at the time of diagnosis and 500 rads of radiation on each of the first three days. After a four-day rest, radiation therapy was continued at 300 rads to a total dose of 3,000 rads. The effects of this new protocol on the patient's motor abilities did not differ from those of previous protocols, namely, 47 of 83 patients (57%) were ambulatory after treatment, with no responses in patients totally paraplegic before treatment. However, early administration of high doses of dexamethasone substantially ameliorated pain in the majority of patients, with relief often coming within hours after the drug was given. On the basis of these data, we recommend high doses of adrenocorticosteroids combined with radiation therapy for acute treatment of spinal cord compression. The optimum fractionation schedule for radiation therapy is not established.

Multilevel vertebral hemangiomas: two episodes of spinal cord compression at separate levels 10 years apart.

This case report presents a 66-year-old woman with multiple vertebral hemangiomas causing spinal cord compression at different levels with a long symptom-free interval between episodes of compression. She presented with back pain and progressive weakness and numbness in her lower limbs for 3 months. Ten years earlier, she had had a symptomatic T4 vertebral hemangioma operated successfully, and had made a full recovery. Magnetic resonance imaging (MRI) of the thoracic and lumbar spine revealed multiple thoracic and lumbar vertebral hemangiomas. Extraosseous extension of a hemangioma at T9 was causing spinal cord compression. Selective embolization was performed preoperatively, and cord decompression was achieved via anterior T9 corpectomy. The patient's neurological status improved rapidly after surgery. After a course of radiotherapy, she was neurologically intact and could walk independently. One year later, MRI showed complete resolution of the cord edema at T9, and showed regression of the high signal intensity that had been observed at unoperated levels. These findings indicated diminished vascularity and reduced aggression of the tumor.

Cervical spinal cord compression and the Hoffmann sign.

Little information exists about the ability of the Hoffmann sign to predict cervical spinal cord compression. The objective of this study was to determine the correlation between the Hoffmann sign and cervical spinal cord compression in a consecutive series of patients seen by a single spine surgeon. All new patients with complaints related to their cervical spine were included. Hoffmann sign was elicited by flicking the nail of the middle finger. Any flexion of the ipsilateral thumb and/or index finger was considered positive. All imaging studies were reviewed for spinal cord compression. Cord compression was defined as flattening of the AP diameter of the spinal cord coexisting with obliteration of CSF around the cord compared to normal levels. Of 165 patients, 124 patients had imaging of their spinal canal. Review by the spine surgeon found sensitivity of the Hoffmann sign relative to cord compression was 58%, specificity 78%, positive predictive value 62%, negative predictive value 75%. 49 studies were also read by a "blinded" neuroradiologist, the sensitivity was 33%, specificity 59%, positive predictive value, 26%, negative predictive value 67%. Although attractive as a simple method of screening for cervical spinal cord compression, the Hoffmann sign, in the absence of other clinical findings, is not in our experience a reliable test.

Spinal-cord compression in myeloma.

Clinical records of 47 patients in whom spinal-cord compression was the presenting feature of plasma-cell myeloma were analysed retrospectively. Patients were referred during 1954-78. Median survival was 30 months and prognosis was best for those in whom the site of cord compression was the thoracic region. Early laminectomy and decompression followed by adequate radiotherapy resulted in complete or good partial response in over a third of patients who presented with complete paraplegia. Improvements in supportive care and more effective chemotherapy allow spinal-cord compression in myeloma to be treated promptly and vigorously, thus improving duration and quality of survival in a substantial proportion of patients.
