Abstract
✓The authors present a rare case of cervical myelopathy caused by dropped head syndrome. This 68-year-old woman presented with her head hanging forward. After 1 month, she was admitted to the medical service because of head drop progression. Examination of biopsy specimens from her cervical paraspinal muscles showed nonspecific myopathic features without inflammation, and isolated neck extensor myopathy was diagnosed. The patient’s condition did not respond to the administration of corticosteroids. During follow up as an outpatient, the patient’s head drop continued to gradually progress. At 1 year after onset, she developed bilateral weakness of the upper and lower extremities, clumsiness of the hands, and gait disturbance. A radiograph of the cervical spine obtained in a standing position showed a pronounced kyphotic deformity and instability at the level of C4–5. Magnetic resonance imaging demonstrated spinal cord compression at C-3 and C-4. The patient underwent a C3–4 laminectomy and occipitocervicothoracic fixation. Gait and hand coordination gradually improved, and she was able to walk with no support 1 month postoperatively. Surgical fixation was beneficial in this patient with dropped head syndrome, myelopathy, and cervical instability.

Abstract
Extramedullary tumors, also known as granulocytic sarcomas (GS), occur most frequently in acute myelogenous leukemia (AML). They may signal the onset of the accelerated phase of chronic myelogenous leukemia (CML) or the blastic transformation of a myeloproliferative disorder. Occasionally, a GS may be the presenting sign of undiagnosed AML, and rarely the presenting sign of undiagnosed CML or aleukemic leukemia. Paraplegia due to a spinal cord GS is an extremely rare presentation of undiagnosed leukemia. This is the first case report of paraplegia as the presenting manifestation of extramedullary megakaryoblastic transformation of previously undiagnosed CML. A 53-year-old woman reported back pain for 6 days, rapidly progressing to paraplegia. Physical examination noted a large abdominal mass and flaccid paralysis in both lower extremities. Spinal MRI revealed a T4-T6 vertebral mass causing spinal stenosis and cord compression. Tumor debulking and laminectomy were performed emergently. The tumor consisted of noncohesive blast cells. The CBC revealed a leukocyte count of 238,300/microl and a differential consistent with CML. Reexamination of the patient found that the abdominal mass was a giant spleen. Further immunohistochemical studies of the tumor were consistent with extramedullary acute megakaryoblastic blast transformation of CML. Although extramedullary blast crises herald the accelerated phases in approximately 10% of CML cases, megakaryoblastic blast transformation of CML accounts for less than 3% of these cases. The combination of acute paraplegia and megakaryoblastic transformation in a previously undiagnosed patient with CML is extremely rare and may pose a diagnostic dilemma.

Abstract
THE NEUROLOGICAL MANIFESTATIONS of cervical spondylosis include symptomatic compression of the spinal cord (myelopathy), nerve roots (radiculopathy), or a combination of the two (myeloradiculopathy). The term myeloradiculopathy herein defines these often indistinct and inseparable entities. The pathophysiology of myeloradiculopathy is multifactorial in nature, and the natural history of untreated myeloradiculopathy is not clearly defined. We review the signs, symptoms, and clinical findings of cervical myelopathy, radiculopathy, and myeloradiculopathy. Standard grading techniques are also reviewed.

Abstract
AbstractCERVICAL SPONDYLOSIS IS the most common progressive disorder in the aging cervical spine. It results from the process of degeneration of the intervertebral discs and facet joints of the cervical spine. Biomechanically, the disc and the facets are the connecting structures between the vertebrae for the transmission of external forces. They also facilitate cervical spine mobility. Symptoms related to myelopathy and radiculopathy are caused by the formation of osteophytes, which compromise the diameter of the spinal canal. This compromise may also be partially developmental. The developmental process, together with the degenerative process, may cause mechanical pressure on the spinal cord at one or multiple levels. This pressure may produce direct neurological damage or ischemic changes and, thus, lead to spinal cord disturbances. A thorough understanding of the biomechanics, the pathology, the clinical presentation, the radiological evaluation, as well as the surgical indications of cervical spondylosis, is essential for the management of patients with cervical spondylosis.

Abstract
COMPRESSION OF THE spinal cord by the degenerating cervical spine tends to lead to progressive clinical symptoms over a variable period of time. Surgical decompression can stop this process and lead to recovery of function. The choice of surgical technique depends on what is causing the compression of the spinal cord. This article reviews the symptoms and assessment for cervical spondylotic myelopathy (clinically evident compression of the spinal cord) and discusses the indications for decompression of the spinal cord anteriorly.

Abstract
We determined whether the benefits of directed rehabilitation for pain, depression, and satisfaction with life persisted for veterans who were nonambulatory after spinal epidural metastasis (SEM) treatment. Twelve consecutive veterans (paraplegic after SEM treatment) who received 2 weeks of directed rehabilitation were compared with a historical control group of thirty paraplegic veterans who did not receive rehabilitation. Subjects were followed until death. Pain levels, depression, satisfaction with life, and consumption of pain medication were measured. Subjects who received rehabilitation had less pain, consumed less pain medication, were less depressed, and had higher satisfaction with life. The benefits to the rehabilitated subjects persisted until their deaths. We conclude that spinal cord injury rehabilitation for nonambulatory subjects with SEM produces persistent benefits for pain, depression, and satisfaction with life.

Abstract
Waldenstrom's macroglobulinemia (WM) is a rare lymphoplasmacytic lymphoma characterized by a wide range of clinical presentations related to direct tumor infiltration and the production of IgM. Most commonly it presents with cytopenia, hepatosplenomegaly, lymphadenopathy, constitutional symptoms, and hyperviscosity syndrome. We report a case of WM in an 81-year-old man who initially presented with severe back pain. The patient had no peripheral lymphadenopathy or hepatosplenomegaly and his peripheral blood smear was normal. MRI of the spine revealed an epidural mass causing spinal cord compression at T9. Surgical decompression was performed and pathological analysis of the mass revealed a lymphoproliferative B-cell process. The diagnosis of WM was established after cytomorphologic and immunohistochemical analysis of the patient's bone marrow revealed the presence of a lymphoid/lymphoplasmacytoid-like bone marrow infiltrate along with an elevated serum IgM level. The patient responded both clinically and serologically to local radiotherapy. This case is unusual because the patient lacked all common clinical features of WM. This is the first reported case of epidural spinal cord compression as the initial manifestation of WM, adding to the spectrum of clinical presentations seen in this disease.

Abstract
BACKGROUND Percutaneous vertebroplasty (PVP) represents a minimally invasive option which is gaining in importance for the treatment of vertebral compression fractures (VCF) and osteolysis of the spine. This article describes the indications for its use, peri-interventional imaging, technique, and results of PVP. MATERIAL AND METHODS The current guidelines for performance of PVP are explained in accordance with the "Interdisciplinary Consensus Paper on Vertebroplasty and Kyphoplasty" of the German Professional Associations and the 2005 CIRSE Guidelines. The results of our own study carried out in 2002 are compared to the complication rates and clinical outcomes reported in the literature. RESULTS Painful osteoporotic VCF and osteolysis within the vertebral body due to metastases and multiple myeloma are indications for PVP. Absolute contraindications are, in particular, asymptomatic VCF, alleviation of pain by drug treatment, therapy-refractory coagulopathies, allergies to cement components, and active infections. MRI or CT is indicated before undertaking PVP to assess the fracture age, to exclude other causes of pain, and to evaluate the posterior edge of the vertebral body. High-quality mono- or biplanar fluoroscopy--preferably in combination with CT (fluoroscopy)--is necessary for PVP to minimize the risk of cement leakage. A clear reduction in pain [mean reduction of 6.1 points (VAS)] is achieved in 86-92% of the patients with PVP. Our own study treating 58 patients (mean follow-up 323+/-99 days) revealed a clear alleviation of pain in 77% [-5.7 points (VAS)]. CONCLUSION PVP constitutes a safe and effective minimally invasive treatment approach to stabilize and reduce acute and chronic back pain due to osteoporotic VCF and tumor-associated osteolysis.

Abstract
The authors describe a technique for the relief of spinal cord compression associated with congenital kyphoscoliosis. A 13-year-old girl with congenital cervicothoracic kyphoscoliosis had undergone in situ fusion; spastic paraparesis and bladder disturbance developed postoperatively. Spinal cord detethering and posterolateral decompression temporarily arrested the neurological deterioration; however, the patient's condition then progressed to paraplegia with a partial sensory level at L-1. Imaging demonstrated persisting cord compression at the apex of the kyphotic curve. Transvertebral transposition of the spinal cord was performed using sagittal vertebrotomies, preserving the lateral aspects of the vertebral bodies, pedicles, and fusion mass. By 2 years postoperatively she had recovered normal sensation and good bladder function and was walking unaided. Transposition of the spinal cord may be used to relieve spinal cord compression associated with complex spinal deformities.

Abstract
This report describes a 66-year-old man who presented with progressive paraparesis after a fall. Magnetic resonance imaging showed an acute spinal hematoma at T11-12 with spinal cord compression. The patient underwent an emergency left T11-12 hemilaminectomy. The hematoma was subarachnoid and the source of bleeding was an injured radicular vein. To the best of our knowledge, this is the first reported case of traumatic spinal subarachnoid hematoma. We discuss the possible mechanism and our case illustrates an injured radicular vein can be a source of traumatic spinal subarachnoid hematoma.

Abstract
OBJECTIVE
Metastasis from lung cancer to the conus medullaris has never been reported in the English literature, although three cases have appeared in the French and Japanese literature. Our case report is unique because the patient presented with a lumbar radiculopathy, an atypical presentation that was found to be caused by metastasis from lung cancer to the conus medullaris. A critical review of the pertinent literature related to metastatic neoplasms to the conus medullaris is also presented.
CLINICAL PRESENTATION
We report the case of a 54-year-old man who presented with an L5 radiculopathy and was initially found to have a small disc herniation at L4–L5 on magnetic resonance imaging scans, which was ruled out as the case of his initial symptoms. In 3 weeks, the symptoms progressed with the development of urinary incontinence and right leg weakness. A magnetic resonance imaging scan of the lumbar spine showed a tumor at the conus medullaris.
INTERVENTION
The patient underwent a laminectomy with removal of the tumor. Pathological examination of the tumor showed infiltrating differentiated adenocarcinoma. A 2.5 cm lung mass in the right middle lobe with surrounding adenopathy was found on a computed tomographic scan of the chest. The patient died 4 months later from systemic involvement and progression of his lung disease.
CONCLUSION
This case report illustrates the rare presentation of a lumbar radiculopathy caused by a metastatic tumor to the conus medullaris. This was the first presentation for the diagnosis of lung cancer in this patient.

Abstract
Spinal cord injury (SCI) pain exhibits many symptoms associated with peripheral neuropathic pain, including increased tactile hypersensitivity. One novel approach to ameliorate SCI pain is the use of cannabinoid (CB) ligands. The current study evaluated the efficacy of the nonselective CB receptor agonist WIN 55,212-2 on tactile hypersensitivity in rats following a brief compression to the thoracic spinal cord. The withdrawal thresholds of the hind paws following SCI were significantly decreased, indicating tactile hypersensitivity. Systemic injection of WIN 55,212-2 increased withdrawal thresholds in a dose-dependent manner. Pretreatment with the CB(1) receptor subtype-selective antagonist AM 251 completely abolished the antinociceptive effect of WIN 55,212-2 whereas pretreatment with the CB(2) receptor subtype-selective antagonist AM 630 did not alter the antinociceptive effect of WIN 55,212-2. These data indicate that a CB(1)-selective agonist may be novel therapeutic treatment for clinical SCI pain.

SETTING National Cheng Kung University Hospital, Tainan, Taiwan. METHODS A 4-month-old boy who initially presented with irritable crying, neck stiffness, and fever followed by progressive quadriparesis. Magnetic resonance imaging (MRI) of the spine disclosed a space-occupying lesion on the right posterior-lateral aspect of the cervicothoracic spinal canal. Laminectomy with reconstruction in situ from C4 to T4 was performed 5 days after the onset of symptoms. RESULTS The boy had gradual improvement of his neurological status. Follow-up visit 1 year later, the infant's growth and development was within normal limit without any neurological deficits; his repeat MRI showed complete fusion of each implanted lamina and well expansion of the spinal cord. CONCLUSIONS Prompt surgical decompression is valuable, irrespective of the time interval between symptom onset and operation in infant.

Abstract
Detailed analysis of the structural changes that follow human clinical spinal cord injury is limited by difficulties in achieving adequate tissue fixation. This study bypasses this obstacle by examining the spinal cord from paraplegic domestic animals, enabling us to document the ultrastructural changes at different times following injury. In all but one case, injury resulted from a combination of contusion and compression. There was infarction and hemorrhage, followed by gray matter destruction and the rapid development of a variety of white matter changes including axon swelling and myelin degeneration. Axons greater than 5 microm in diameter were more susceptible to degenerative changes, whereas smaller axons, particularly those in the subpial region, were relatively well preserved. Demyelinated axons were seen within 2 weeks after injury and, at later time points, both Schwann cell and oligodendrocyte remyelination was common. More subtle white matter abnormalities were identified by examining sagittal sections, including focal accumulation of organelles in the axoplasm and partial and paranodal myelin abnormalities. These observations serve to validate observations from experimental models of spinal contusion but also highlight the complexity of naturally occurring (ie, clinical) spinal injury. They also raise the possibility that focal abnormalities such as paranodal demyelination may contribute to early axonal dysfunction and possibly to progressive tissue damage.

Abstract
STUDY DESIGN Case studies of patients with cervical spondylosis with unilateral upper extremity amyotrophy. OBJECTIVE To clarify the surgical outcome of posterior decompression for this amyotrophy. SUMMARY OF BACKGROUND DATA Cervical spondylosis sometimes causes a characteristic severe muscular atrophy without sensory disturbance or lower-extremity dysfunction, which is the so-called "cervical spondylotic amyotrophy." However, response to treatment, especially to posterior decompression, has not been well understood. METHOD This study included 32 patients. All underwent posterior cervical laminoplasty, and 22 patients had an additional foraminotomy. Preoperative and postoperative muscle power and results of imaging and electrophysiologic studies were evaluated. The follow-up period averaged 78 months. Whether impingement was against the ventral nerve root (VNR) or anterior horn (AH) in the spinal cord was assessed according to these findings. These cases were divided into proximal type and distal type according to the most severely atrophic muscle and compared statistically. RESULTS Severe preoperative muscle atrophy was observed in the deltoid and biceps muscles of 24 patients (proximal type) and in the forearm and hand muscles of 8 patients (distal type). Impingements against the VNR and AH were observed in 21 and 28 cases, respectively, and 17 cases had impingement of both the VNR and AH. Improvements in muscle atrophy after surgery were observed in 25 cases. In proximal-type patients, muscle power improved in 92% of cases but was improved in only 38% of the distal-type cases. CONCLUSIONS Laminoplasty and foraminotomy were effective in the treatment of most patients with this syndrome, although the outcome in the distal type was inferior to that in the proximal type.

Abstract
BACKGROUND A 47-year-old male underwent resection of a left-shoulder melanoma in 1997. In November 2004 he was found to have multiple brain lesions and adrenal, lung, and bone metastases, and in January 2005 underwent resection of his symptomatic right parietal lobe lesion and subsequent whole-brain radiation. In February 2005 he experienced headaches and word-finding difficulty and was found to have four progressive brain lesions on MRI. These were resistant to conventional radiotherapy and were treated with stereotactic radiosurgery. The patient later developed an obstruction of the jejunum and underwent resection of multiple abdominal masses. In April 2005, the patient commenced temozolomide and underwent radiation therapy to the left arm for pain thought to be caused by an increase in size of his melanoma metastasis. In August 2005 the patient reported persistent and worsening arm pain, despite a further course of radiotherapy in June 2005. INVESTIGATIONS Physical examination including a thorough neurological examination, radiography, X-ray, CT scan, and MRI. DIAGNOSIS Metastatic melanoma to the cervical spine (C7 vertebra) with spinal cord compression. MANAGEMENT Involved field radiotherapy, temozolomide, opioids, gabapentin, corticosteroids, and Cyberknife therapy.

Abstract
OBJECTIVE The authors report on the first case of a spinal intradural extramedullary cystic teratoma in an aged patient. These lesions have been reported in adolescents and young adults often with a history of spinal dysraphism. They are believed to be congenital lesions; however, they have also been reported in patients with a history of posterior spinal surgery or lumbar puncture. METHOD An 85-year-old man was evaluated for persistent and progressive lower extremity paresis. His symptoms began after relatively minor trauma. He had no prior lumbar surgeries. Neuroimaging studies revealed an L1-L2 intradural mass. A putative diagnosis of a cystic intradural extramedullary mass was made. A lumbar laminectomy and durotomy were performed. RESULTS A cystic lesion containing hair follicles, cartilage, adipose, and neural tissue was encountered. Pathologic review corroborated the diagnosis of cystic teratoma. CONCLUSIONS The occurrence of cystic teratomas in the absence of previous surgery or lumbar puncture is uncommon. Even rarer are reports of these lesions in aged patients. Of particular interest in this case is the fact that this patient had not undergone any previous lumbar procedures nor did he have a history of spinal dysraphism. Though rare, this entity should be included in the differential of cystic intradural spinal cord lesions.

Abstract
STUDY DESIGN Prospective, comparative study of neurologic outcome in patients with posterior extradural cord compression. OBJECTIVE To compare the results of surgical decompression in patients presenting with neurologic deficit due to posterior element tuberculosis with those due to other causes. SUMMARY OF BACKGROUND DATA Posterior cord compression is a relatively uncommon entity with not much literature published on it. METHODS Over a period of 5 years, 14 patients with extradural posterior cord compression with neurologic deficit were divided into two etiologic groups: 9 patients had Koch's and 5 had other pathologies. All these cases were surgically decompressed posteriorly and the results compared. RESULTS While results of surgery in patients with Koch's were good, with 7 of the 9 patients showing full recovery, outcome in patients with compression due to other causes (tumor/pyogenic infection) was not very satisfactory even after adequate mechanical decompression, with 3 of the 5 cases remaining paraplegic even after surgery. CONCLUSION Posterior cord compression due to nontuberculous causes frequently mimics the picture of Koch's both clinically and radiologically. Prognosis of surgical decompression is good in tuberculous compression but not in other cases.

Abstract
OBJECTIVE The purpose of this study is to present information from a series of patients with imaging findings of encroachment on the cervical spinal cord who were treated with chiropractic cervical manipulation. CASE SERIES There were 27 patients (18 females, 9 males; age range, 23-65, mean age, 44.3 years) with neck and/or arm pain with findings of cervical spinal cord encroachment on magnetic resonance imaging. None of these patients had severe or acute myelopathy or advanced signal changes in the spinal cord indicative of myelomalacia. These patients were treated with a variety of approaches that included some form of cervical manipulation. The mean number of treatments that included manipulation was 12 (range, 2-32). Nineteen patients were treated with high-velocity, low-amplitude "thrust" manipulation, 9 patients were treated with low-velocity muscle energy technique, and 1 patient was treated with both methods. The mean patient-rated subjective improvement at the last follow-up reexamination was 70.0% (range, 10%-100%). From baseline to the last follow-up examination, the mean improvements in outcome measures were as follows: Bournemouth Neck Disability Questionnaire, 23.7 points (31%); Neck Disability Index, 6.4 points; and Numerical Pain Rating Scale, 3.9 points. In 3 patients, there was increased pain after manipulation that lasted from 1 to 4 days. There were no major complications, and in no patient did any increased pain after treatment last more than 4 days. No new neurologic symptoms or signs were seen in any of these patients. CONCLUSION The finding of cervical spinal cord encroachment on magnetic resonance imaging, in and of itself, should not necessarily be considered an absolute contraindication to manipulation. However, because radicular and myelopathic complications to cervical manipulation have been reported in the literature, great care should be taken in all cases, particularly those in which anatomic conditions such as cord encroachment are present.

Abstract
Although pseudoathetosis has been described in various conditions, it has been rarely reported in patients with epidural lesions. We report the first case of a patient with pseudoathetosis caused by a migrated cervical disc. The patient was a 76-year-old woman who presented with progressive clumsiness of the hands and athetotic movements. Electrophysiological studies revealed normal peripheral nerve conduction and delayed and attenuated cortical SEPs. Spinal MRI revealed an epidural mass with gadolinium enhancement at the C3-4 level. An anterior cervical surgery disclosed a migrated disc, and its removal resulted in a marked improvement. Migrated cervical disc should be considered in patients with a profound sensory loss and pseudoathetosis in the hands, because this condition is treatable.

Abstract
Clumsiness of the hands is one of the most common complaints in patients with cervical myelopathy. However, few reports have been published that evaluate hand dysfunction. One hundred and twenty-nine patients (36 women and 93 men) with cervical myelopathy were examined and results compared with those of age- and sex-matched controls. Hand function was evaluated as scores of 10 subtests designed on the basis of various hand activities. Patients with cervical myelopathy obtained significantly lower scores on the hand function test in each age-group than controls. There was good correlation between hand function scores and the extent of cervical myelopathy. Therefore, the hand function test is a useful battery to objectively and quantitatively evaluate impairment of cervical myelopathy, although longitudinal studies are needed to determine its practical usability.
