Abstract
Intramedullary glioblastomas in adult patients have rarely been reported. We describe magnetic resonance (MR) imaging findings, include findings on diffusion tensor imaging (DTI) and dynamic susceptibility contrast perfusion weighted imaging (PWI) in a case of autopsy-confirmed glioblastoma in a 72-year-old man. Serial MR examinations, DTI and PWI, and positron emission tomography examinations were performed. The tumor involved the medulla oblongata and the upper cervical spinal cord. Traditional MR imaging findings were unclear with regard to the differential diagnosis between intramedullary glioma or a tumefactive demyelinating lesion, but an increase in regional cerebral blood volume and a decrease in fractional anisotropy of the lesion correctly suggested a high-grade glioma. MR PWI and DTI may prove helpful to diagnose glioblastoma of the cervical cord when other imaging features are inconclusive.

Surgical strategies for managing foraminal nerve sheath tumors: the emerging role of CyberKnife ablation. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2009; 19:242-56. [PMID: 19798517 DOI: 10.1007/s00586-009-1160-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2008] [Revised: 07/18/2009] [Accepted: 08/30/2009] [Indexed: 12/15/2022]
Abstract
Sixteen Stanford University Medical Center (SUMC) patients with foraminal nerve sheath tumors had charts reviewed. CyberKnife radiosurgery was innovative in management. Parameters were evaluated for 16 foraminal nerve sheath tumors undergoing surgery, some with CyberKnife. Three neurofibromas had associated neurofibromatosis type 1 (NF1). Eleven patients had one resection; others had CyberKnife after one (two) and two (three) operations. The malignant peripheral nerve sheath tumor (MPNST) had prior field-radiation and adds another case. Approaches included laminotomy and laminectomies with partial (three) or total (two) facetectomies/fusions. Two cases each had supraclavicular, lateral extracavitary, retroperitoneal and Wiltze and costotransversectomy/thoracotomy procedures. Two underwent a laminectomy/partial facetectomy, then CyberKnife. Pre-CyberKnife, one of two others had a laminectomy/partial facetectomy, then total facetectomy/fusion and the other, two supraclavicular approaches. The MPNST had a hemi-laminotomy then laminectomy/total facetectomy/fusion, followed by CyberKnife. Roots were preserved, except in two. Of 11 single-operation-peripheral nerve sheath tumors, the asymptomatic case remained stable, nine (92%) improved and one (9%) worsened. Examinations remained intact in three (27%) and improved in seven (64%). Two having a single operation then CyberKnife had improvement after both. Of two undergoing two operations, one had symptom resolution post-operatively, worsened 4 years post-CyberKnife then has remained unchanged after re-operation. The other such patient improved post-operatively, had no change after re-operation and improved post-CyberKnife. The MPNST had presentation improvement after the first operation, worsened and after the second surgery \and CyberKnife, the patient expired from tumor spread. In conclusion, surgery is beneficial for pain relief and function preservation in foraminal nerve sheath tumors. Open surgery with CyberKnife is an innovation in these tumors' management.

Abstract
Spinal meningiomas are uncommon entities that fortunately burden only a small minority of patients. Notwithstanding their overwhelmingly benign propensity, the occurrence of extramedullary meningioma may nonetheless cause significant morbidity and possible mortality. The consideration therefore, of spinal meningioma in the differential of patients presenting with radiculopathy or complaints of chronic back or neck pain should not be disregarded. The rapidity of diagnosis and the first neurosurgical encounter are cornerstones in patient longevity and neurological preservation. The advent of microsurgical techniques and magnetic resonance imaging and surgical techniques has notably improved clinical outcomes over the past two decades. However, surgical candidacy may be limited, particularly in those patients with significant preexisting medical comorbidities, aggressive or recurring tumors, or multiple lesions. Alternative management strategies such as stereotactic radiosurgery or less invasive surgical techniques are currently underway in clinical practice. A review on neurosurgical diagnosis and treatment modalities in the management of spinal meningioma is therefore pertinent.

Abstract
The medullary conus represents a distinct entity of the spinal cord regarding its anatomical, clinical and microsurgical features. An overview of the pathologic processes of this region is provided. Epidemiological, clinical and neuroradiological characteristics of neoplastic (glial tumors, non-glial tumors, metastasis, primary melanomas) and non-neoplastic lesions (granulomatous lesions, abscess, parasitic infections, vascular, demyelinating and dysembryogenetic lesions) are discussed. Main MR imaging characteristics used to differentiate neoplastic from non-neoplastic lesions consist in pathological spinal cord expansion, gadolinium-enhancement and tumoural cyst formation. Management strategies differ substantially, depending on the kind of lesion. According to the suspected pathological entity radical resection, biopsy or conservative treatments are reasonable options. Intraoperative electrophysiological monitoring is a fundamental part of the surgical setting.

Abstract
OBJECTIVE This report discusses a patient with a pathologic fracture of the C2 vertebra secondary to osteolytic metastasis from squamous cell carcinoma of the lung. CLINICAL FEATURES The patient was a 68-year-old man with a chief complaint of neck pain who was referred by his physician to a chiropractic office. The initial onset of neck pain began after a forceful sneeze that resulted in a sensation of "a twig snapping" in the neck. Radiographs revealed osteolytic destruction and pathologic fracture of the C2 spinous process. INTERVENTION AND OUTCOME The patient was referred back to his primary care physician, who then referred him to an oncologist, who immediately initiated a course of radiation therapy and pain medication. Palliative care by the chiropractor consisted of soft tissue massage of the cervical spine musculature to treat associated muscle spasms and pain. The patient responded well to gentle myofascial therapy. However, the osteolytic destruction of the C2 posterior elements progressed, resulting in an unstable subluxation of C2 and associated cord compression. The spine was stabilized with a rigid collar, but the metastatic destruction progressed, eventually resulting in quadriplegia and subsequent death from respiratory distress. CONCLUSION Patients with a history of cancer complaining of new onset of back or neck pain should be assumed to have vertebral metastasis until proven otherwise. Trivial trauma should be taken seriously in these cases and investigated with appropriate clinical, laboratory, and imaging examinations. Vertebral malignancies may be a contraindication to spinal manipulation; however, the chiropractic physician plays a significant role in early detection and diagnosis.

Abstract
Although spinal tumors are uncommon, they may reduce survival or cause serious functional disorders in the extremities. Metastatic spinal tumors from malignant tumors can induce symptoms of spinal cord compression, such as paraplegia, quadriplegia, and vesicorectal disturbance, which are aggravated with progression of the diseases and time. We report a patient with hepatocellular carcinoma (HCC) who was suspected of having spinal lesions based on neurological findings, and a metastatic spinal tumor was found by imaging examination. Assuming that metastasis had occurred at the time lumbar pain developed, the patient reached the level of gait disturbance within only 4 mo, showing a rapid advancement of symptoms. If early diagnosis had been possible, treatment could be performed before acute myelopathy progressed to complete paralysis. We speculate that the terminal stage of HCC is not only liver failure associated with intrahepatic lesions but also metastasis to other regions, treatment for individual pathologies therefore, will be needed, which constitutes an important issue.

Abstract
Intradural spinal-cord tumours are an uncommon but important consideration in the differential diagnosis of patients with back pain, radicular pain, sensorimotor deficits, or sphincter dysfunction. Intradural spinal tumours can be divided into intramedullary and extramedullary spinal-cord tumours on the basis of their anatomical relation to the spinal parenchyma. The heterogeneous cell composition of the intradural compartment allows the formation of neoplasms, arising from glial cells, neurons, and cells of spinal vasculature. Additionally, developmental tumours, metastases, and intradural extension of extradural tumours are represented. In this Review, we discuss the published work on intradural spinal-cord tumours in terms of epidemiological, radiographic, and histological characteristics. Surgical and adjuvant treatment strategies are also reviewed.

Abstract
Although it is quite rare, second primary neoplasms in cancer patients may present with the signs and symptoms of malignant spinal cord compression. Primary spinal cord tumours in the cancer patients may be deceptive and considered as the recurrent first cancer. Therefore, it should be precisely differentiated and appropriately managed. We report such a case of intramedullary ependymoma of the cervical spinal cord mimicking metatstatic recurrent lymphoma and causing cord compression. A 50-year-old man developed intramedullary ependymoma of the cervical spinal cord 1.5 years following chemoradiation for Waldeyer's ring lymphoma. He presented with a 2-month history of neck pain, progressive upper- and lower-extremity numbness and weakness, and bowel and bladder dysfunction. Magnetic resonance imaging revealed an intramedullary expansive lesion extending from C4 to C6 levels of the cervical spinal cord. The clinical and radiological findings were suggestive of malignant process. A comprehensive investigation failed to detect another site of disease. He underwent operation, and the tumour was subtotally resected. The patient's neurological deficits improved subsequently. The development of the intramedullary ependymoma following treating lymphoma has not been reported. We describe the clinical, radiological and pathological findings of this case and review the literature.

Abstract
Intramedullary spinal tumours are uncommon lesions that can cause significant difficulties in the differential diagnosis between inflammatory diseases such as multiple sclerosis and acute disseminated encephalomyelitis, and vascular malformations or neoplasms. We report five cases in which the history and the clinical symptoms suggested an inflammatory process of the spinal cord but the MRI characteristics were those of neoplastic lesions. Both non-neoplastic and neoplastic intramedullary lesion may have very similar symptoms, and even CSF abnormalities, but in every one of our cases, a more detailed history and longer observation of the clinical course would have led to the correct diagnosis; in such problem cases, empirical treatment and a follow-up MRI after a month's observation would be a more prudent approach providing that the patient is not rapidly deteriorating.

Abstract
The aim of this study was to assess the time to diagnosis in patients with intraspinal tumors and to assess factors contributing to a long delay in some patients. Patients who were admitted at our hospital over a 15-year period (1986-2000) with an intraspinal (either intradural or extradural) tumor were included. Records of patients were studied for variables such as sex, age, diagnosis, date of diagnosis, initial symptoms, symptoms at diagnosis, level of tumor, original diagnosis and diagnostic technique [CT-myelography, CT-caudography or magnetic resonance imaging (MRI)]. The median time to diagnosis of 108 patients with an intraspinal tumor was 12.3 months (range: 4 days-14.4 years). Most common initial symptoms were back and/or neck pain, pain radiating to one extremity and walking disturbances. There was no distinctive clinical pattern between intramedullary and extramedullary tumors regarding initial symptoms. At the time of diagnosis, patients presented with moderate to severe neurological deficits: weakness in one extremity in 26%, sphincter disturbance (20%) and paraparesis (12%). Improved imaging of the spinal cord by MRI did not result in earlier detection of the intraspinal tumor. The time to diagnosis is explained by non-specific and slowly progressing signs and symptoms. A high rate of clinical suspicion should be present to diagnose an intraspinal tumor at an early stage.

Abstract
Spinal intradural tumors are uncommon lesions but may cause significant morbidity. In establishing the differential diagnosis for a spinal lesion, location, age, and the patient's clinical presentation are important. Magnetic resonance imaging plays a central role in the visualization of spinal tumors, easily allowing tumors to be classified as extradural, intradural extramedullary, or intramedullary which is very useful in tumor characterization. We describe intradural tumors; the majority is extramedullary, with nerve sheath tumors being the most frequent. Intramedullary tumors are uncommon spinal tumors. Ependymomas and astrocytomas comprise the majority of this group. Typical imaging features of both intradural extramedullary and intramedullary tumors are described.
