1/90. Spinal lesions, paraplegia and the surgeon.Thirty-six patients with spinal cord lesions and varying degrees of paraplegia were seen by the surgical team at the Angau Memorial Hospital, Lae, over a thirty month period. Because the continued presence of a spinal lesion may lead to progressive cord destruction and ischaemic myelopathy, prompt treatment is advocated. The depressing results that have followed treatment of fracture dislocations of the cervical spine and secondary neoplasm with paraplegia is recorded and some suggestions are made that may improve the outlook in future cases. Early and major surgery is advocated in the treatment of spinal abscesses, tumours, Pott's paraplegia and unstable fracture dislocations of the lumbar spine.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/90. spinal cord compression caused by adjacent adenocystic carcinoma of the skin.Adenocystic carcinomas are malignant tumours that arise from the major accessory salivary glands. Cutaneous involvement can result from direct extension from a salivary gland neoplasm. Cutaneous adenocystic carcinomas remote from adjacent salivary tissue are rare. We present the case of an elderly patient with primary cutaneous adenoid cystic carcinoma causing spinal cord compression at the L1-L2 level. The patient was operated on and the tumour totally removed. No similar cases have been found in our review of the literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/90. Simultaneous development of a pineal tumor and an intradural spinal mass during remission of acute lymphocytic leukemia.A small percentage of children with acute lymphocytic leukemia experience relapse in the central nervous system in spite of prophylaxis. Diffuse leptomeningeal infiltration is common but an intracranial leukemic mass or spinal cord involvement is a rare manifestation. We report a child with acute lymphocytic leukemia who simultaneously developed a pineal tumor and an intradural spinal cord mass as her first relapse. She was successfully managed by comprehensive combined treatment including peripheral blood stem cell transplantation. She remains in continuous complete remission for more than 5 years without further evidence of neurological sequelae.- - - - - - - - - - ranking = 20.012439198014keywords = central nervous system, nervous system (Clic here for more details about this article) |
4/90. Primary intradural extramedullary ependymoma: case report and review of the literature.STUDY DESIGN: The authors report the ninth case in the literature of a primary intradural extramedullary ependymoma of the spinal cord. OBJECTIVE: To discuss surgical treatment and the physiopathologic hypothesis of this localization on the basis of the results of the present study and a review of the literature. SUMMARY OF BACKGROUND DATA: ependymoma is a glial tumor known to arise in the central nervous system. Intradural extramedullary location of this neoplasm has been exceptionally described previously. methods: A 43-year-old woman was admitted to the authors' institution with an history of progressive paraplegia. neurologic examination showed sensory loss below T1 and bladder disturbances. magnetic resonance imaging revealed an enhanced thoracic intradural extramedullary tumor, extending from T1-T8. No other lesion in the central nervous system was found. Emergency surgical resection was performed. RESULTS: Surgery gave confirmation of an encapsulated extramedullary tumor without attachment to the spinal cord or to the dura mater. Total removal was achieved under microscope. The postoperative course was uneventful, with complete neurologic recovery 3 months later. The patient has been well for 24 months of follow-up evaluation, without evidence of recurrence on magnetic resonance images. Histologic examination revealed the tumor as a benign ependymoma. CONCLUSION: The encapsulated feature, the lack of attachment to the central nervous system, and the absence of other neoplastic processes within the brain or the spinal cord suggested that this lesion is a primary tumor developed from ectopic ependymal cells.- - - - - - - - - - ranking = 61.037317594042keywords = central nervous system, nervous system, neoplasm (Clic here for more details about this article) |
5/90. Calcifying pseudoneoplasms of the spine with myelopathy. Report of two cases.The authors describe two cases of calcifying pseudoneoplasms, rare degenerative lesions that mimic tumor or infection. One case involved the cervical spine and the second the thoracic spine. Both patients experienced progressive myelopathy from extradural compression of the spinal cord. The radiological evaluation, pathological findings in the lesions, treatment, and follow up are described. Total or subtotal excision can relieve symptoms and prevent recurrence of this lesion.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
6/90. Metastatic testicular cancer presenting as spinal cord compression: report of two cases.BACKGROUND: Testicular cancers are heterogenous neoplasms often found in young adults. They tend to metastasize to the chest, retroperitoneum, or neck, but rarely to the long bones or skeleton. However, they can cause neurologic compromise and should be considered in young male patients who present with symptoms of a spine lesion and no known primary cancer. methods: Two patients presented with back pain and a rapid progression of lower extremity weakness. Both underwent radiographic workup and emergency surgery. Metastatic workup revealed testicular cancer and widespread metastases. RESULTS: Both patients improved neurologically after surgery, but neither regained the ability to ambulate independently. They both underwent chemotherapy. One patient is alive at 1 year follow-up; the other died 9 months after surgery of widespread metastases. CONCLUSIONS: Vertebral metastases from testicular tumors, although rare, should be considered in young men presenting with spinal cord compression. work-up should include magnetic resonance imaging (MRI) of the spine and computed tomography (CT) of the chest, abdomen, and pelvis. Urgent intervention may be required, as these two cases show that loss of neurologic function can be rapid and permanent.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/90. Double ependymoma of the filum terminale.Myxopapillary ependymoma of the filum terminale and conus medullaris are relatively common spinal intradural neoplasms in adults, only 8-14% affecting children. We describe a case of a 15-year-old girl with two myxopapillary ependymomas of the filum terminale. Although cases of two such tumours have been described in adults, we have not found any similar paediatric cases in the literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/90. Extradural spinal cavernous haemangioma: case report and review of the literature.Cavernous haemangiomas (cavernomas) are uncommon vascular malformations of the central nervous system (CNS). They occur in both sporadic and familial forms and may involve any site in the CNS. Spinal cavernomas are less common than intracerebral lesion s, and examples in the spinal epidural space are rare. A case of a solitary sporadic spinal extradural cavernoma in a 41 year old male which presented as progressive lower limb numbness and weakness is reported. The literature regarding spinal cavernomas is reviewed and the symptomatology, diagnostic evaluation, pathology, management and prognosis of these lesions are discussed.- - - - - - - - - - ranking = 20.012439198014keywords = central nervous system, nervous system (Clic here for more details about this article) |
9/90. Inflammatory myofibroblastic tumor with CNS involvement.BACKGROUND: Inflammatory myofibroblastic tumors (IMT) represent a spectrum of neoplasms that occur in the mesentery and retroperitoneum and less frequently in the mediastinum of children and young adults. Transformation into inflammatory fibrosarcoma and metastases are rare. CASE REPORT:We report the case of a 16-year-old patient with an inflammatory myofibroblastic tumor of the mesentery with mediastinal metastases. Partial remission was obtained by chemotherapy with ifosfamide, dactinomycine, and vincristine. Two months later, relapse with infiltration of the meninges developed, and the patient died. CONCLUSION:This case demonstrates unusual features of an IMT: presentation with metastases, excellent response to chemotherapy, dissemination to the CNS.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/90. Epidermal naevus and segmental hypermelanosis associated with an intraspinal mass: overlap between different mosaic neuroectodermal syndromes.The epidermal naevus syndrome is a neurocutaneous syndrome characterised by the association of epidermal naevi with central nervous system, skeletal, ocular or cardiovascular abnormalities. We report on a 1.75-year-old boy who presented with spastic diparesis, a partial paresis of the left forearm and macrocephaly. He had a large epidermal naevus along the cervical spine and a segmental hypermelanosis. MRI studies revealed a large intraspinal mass extending from the lower cervical to the upper thoracic spine. The condition of our patient demonstrates the overlap of the epidermal naevus syndrome with well-defined mosaic neuroectodermal phenotypes such as encephalocraniocutaneous lipomatosis, Feuerstein-Mims syndrome and proteus syndrome. Conclusion: we recommend evaluation of all patients with large epidermal naevi, especially in the head and neck region, for the presence of central nervous system abnormalities or neoplasms.- - - - - - - - - - ranking = 41.024878396028keywords = central nervous system, nervous system, neoplasm (Clic here for more details about this article) |
