1/125. Radiculomyelitis following acute haemorrhagic conjunctivitis.The clinical manifestations and natural history of radiculomyelitis following a newly reported disease--acute haemorrhagic conjunctivitis (AHC)--have been studied in 33 patients in taiwan, and the following observations made: All the patients in this series were adults at ages ranging from 21 to 55 years; the salient initial neurological manifestations were radicular pains and acute flaccid paralysis which developed from five to thirty-seven days after the onset of AHC. In some patients, signs and symptoms indicating involvement of the meninges, cranial nerves and the white matter of the cord were observed; motor paralysis was the most striking feature during the whole clinical course; it consisted of flaccid asymmetrical weakness in one or more limbs, usually being more severe in the lower limbs than in the upper, and often more proximal than distal. Atrophy in the severely affected muscles usually became apparent in the second or third week of the weakness; the prognosis regarding the return of function in the affected muscles was dependent on the severity of the involvement. Permanent incapacitation due to paralysis and muscular atrophy in the affected proximal muscles of lower limbs was the main sequel in severe cases. The pattern and prognosis of flaccid motor paralysis were reminiscent of acute poliomyelitis in which the anterior horn cells of the spinal cord are mainly involved. Pleocytosis ranging from 11 to 270 per mm3 was noted in the majority of the patients when the cerebrospinal fluid was examined within the first three weeks from the onset of neurological symptoms; the total protein level was raised invariably from the second week onwards in all specimens, and remained so throughout the subsequent course as long as the seventh week or later. Tissue culture neutralization tests were performed on the sera from 9 patients; significant rises in the antibody titres (greater than or equal to 1:16) to AHC virus antigens were found in 8 cases, and in 2 of them a fourfold rise in the paired sera was noted. The differentiation of this syndrome from poliomyelitis and from guillain-barre syndrome, the relative freedom of children from neurological complications of AHC and the aetiological relationship of AHC virus to the syndrome have been discussed. It is concluded that this unusual neurological syndrome is caused by the neurovirulent properties of the AHC virus.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
2/125. MRI of enterovirus 71 myelitis with monoplegia.We report two boys diagnosed as having herpangina and hand-foot-mouth disease complicated by monoplegia during the outbreak enterovirus infection in taiwan in 1998. enterovirus 71 was identified in the stool and throat swab; neither polio nor Coxsackie viruses was identified. MRI showed unilateral lesions in the anterior horns of the spinal cord at T11-12 and C2-5. Although the MRI findings and sites of these lesions were similar to those of poliovirus-associated poliomyelitis, the virological data indicated that these boys were infected with enterovirus type 71.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
3/125. Tuberculous radiculomyelitis complicating tuberculous meningitis: case report and review.Tuberculous radiculomyelitis (TBRM) is a complication of tuberculous meningitis (TBM), which has been reported rarely in the modern medical literature. We describe a case of TBRM that developed in an human immunodeficiency virus (hiv)-infected patient, despite prompt antituberculous treatment. To our knowledge, this is the second case of TBRM reported in an hiv-infected patient. We also review 74 previously reported cases of TBRM. TBRM develops at various periods after TBM, even in adequately treated patients after sterilization of the cerebrospinal fluid (CSF). The most common symptoms are subacute paraparesis, radicular pain, bladder disturbance, and subsequent paralysis. CSF evaluation usually shows an active inflammatory response with a very high protein level. MRI and CT scan are critical for diagnosis, revealing loculation and obliteration of the subarachnoid space along with linear intradural enhancement. As in other forms of paradoxical reactions to antituberculous treatment, there is evidence that steroid treatment might have a beneficial effect.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
4/125. MRI of radiation myelitis: a report of a case treated with hyperbaric oxygen.Radiation therapy is commonly applied as a primary or adjuvant therapy for malignancies. One of the major complications following radiation therapy is the necrosis of the otherwise normal surrounding soft tissues and/or bone. Post-radiation myelopathy rarely occurs when the spinal cord is included within the radiation field, in cases of high total radiation doses or for high radiation doses per fractionation. Up until the present, no tolerance dose for the spinal cord has accurately been defined and no treatment has proved satisfactory. Hyperbaric oxygen therapy is already currently used as adjuvant treatment for osteoradionecrosis and for radionecrosis of soft tissues with satisfactory results, whereas results for the treatment of post-attinic myelitis were contradictory. The aim of our report is to describe a case of radiation myelitis with a progressive improvement in the clinicoradiologic picture following hyperbaric oxygen treatment.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
5/125. Acute-onset nontraumatic paraplegia in childhood: fibrocartilaginous embolism or acute myelitis?Fibrocartilaginous embolus causing acute spinal cord infarction is a rare cause of acute-onset paraplegia or quadriplegia. Few cases of survivors have been reported in the neurosurgical literature, with most reports involving postmortem or biopsy findings. There is little information on MRI findings in such patients. We present the youngest patient ever reported, and discuss the important differences between fibrocartilaginous embolus and acute myelitis of childhood. A 6-year-old girl with a history of back pain presented with sudden-onset nontraumatic paraplegia, with a clinical anterior spinal artery syndrome. Initial MRI scan revealed intervertebral disc disease at L1-2 and an incidental thoracic syrinx, but no cause for her acute-onset paraplegia was identified. cerebrospinal fluid and other investigations were all negative. Sequential MRI scans revealed development of spinal cord expansion from T10 to the conus medullaris, with increased cord signal in the anterior aspect of the spinal cord. The intervertebral disc disease was unchanged. The imaging and clinical findings were caused by fibrocartilaginous embolus, which meant there was no need for spinal cord biopsy. The report describes the clinical and imaging criteria for diagnosis of fibrocartilaginous embolus, highlighting the case for avoiding an unnecessary biopsy. The clinical pattern in the paediatric group is discussed, with features differentiating it from acute myelitis of childhood.- - - - - - - - - - ranking = 3keywords = spinal (Clic here for more details about this article) |
6/125. Dural puncture and iatrogenic pneumocephalus with subsequent transverse myelitis in a parturient.PURPOSE: To report a case of transverse myelitis following inadvertent dural puncture and iatrogenic pneumocephalus and any possible causal relationship is explored. CLINICAL FEATURES: A 32-yr-old primigravida developed a severe headache associated with pneumocephalus following accidental dural puncture when the loss of resistance to air technique was used to locate the epidural space. She was treated with oxygen 100% to promote resorption of the air and the headache resolved. One month later she developed a sensory disturbance in her feet. Neurological examination revealed reduced sensation to cold and pain to ankle level and bilateral suppressed knee and ankle reflexes but was otherwise normal. A spinal cord lesion (epidural abscess/hematoma) was excluded with an emergency T1 and T2 weighted magnetic resonance imaging (MRI) scan of the lumbar spine. Over the next 48 hr the sensory disturbance worsened to involve her legs and waist. Examination revealed a sensory loss to waist level, reduced joint position sense and vibration sense in her lower limbs and absent knee and ankle reflexes bilaterally, but normal power in both her legs. A further full length T2 weighted MRI scan of the spine showed a small area of high signal at the level of T3 compatible with transverse myelitis. This was treated with high dose corticosteroids and her symptoms resolved over the next three months. CONCLUSION: The etiology of transverse myelitis after dural puncture in a parturient could not be identified nor could any causal link be established between the dural puncture, pneumocephalus, and subsequent transverse myelitis.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
7/125. toxoplasma gondii myelitis in a patient with adult T-cell leukemia-lymphoma.adult T cell leukemia-lymphoma (ATL) caused by HTLV-I may be associated with severe immunosupression and several opportunistic infections. Toxoplasmic encephalitis is a common central nervous system opportunistic infection in severely immunosupressed patients, however spinal cord involvement by this parasite is rare. In this paper, we report a case of toxoplasmic myelitis in a patient with ATL.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
8/125. Eosinophilic pleocytosis and myelitis related to toxocara canis infection.toxocara canis causes the visceral larva migrans syndrome in which central nervous involvement is rare. We report the case of a 40-year-old woman presenting with a subacute weakness of the right leg and dysaesthesiae in the right Th8-Th10 dermatomas. Spinal magnetic resonance imaging examination showed abnormal hyperintensity within the spinal cord. cerebrospinal fluid analysis revealed eosinophilic pleocytosis. Antibody titres to toxocara canis were higher in the cerebrospinal fluid than in the serum. Treatment using mebendazole led to a complete clinical recovery, normalization of cerebrospinal fluid parameters and improvement in spinal magnetic resonance imaging abnormalities.- - - - - - - - - - ranking = 2.5keywords = spinal (Clic here for more details about this article) |
9/125. spinal cord lesions of myelitis with hyperIgEemia and mite antigen specific IgE (atopic myelitis) manifest eosinophilic inflammation.We report the neuropathological findings of spinal cord specimens obtained from two patients who had localized myelitis with hyperIgEemia and mite antigen specific IgE (atopic myelitis). Both cases showed mild spinal cord dysfunction, and the gadolinium-enhanced area of the isolated spinal cord lesion observed on MRI was biopsied, respectively. Neuropathologically, both cases showed many perivascular lymphocyte cuffings associated with disrupted vessels, and the infiltration of eosinophils in the spinal cord lesions. Both myelin and axons were lost in the lesions, which were associated with astrogliosis. These findings suggest that an allergic mechanism may play a role in this condition.- - - - - - - - - - ranking = 2keywords = spinal (Clic here for more details about this article) |
10/125. Radiation myelitis following allogeneic stem cell transplantation and consolidation radiotherapy for non-Hodgkin's lymphoma.Myelitis is a rare but well documented complication of therapeutic radiation exposure to the spinal cord and is characterized by delayed development of paresthesias, sensory changes and, in severe cases, progressive paresis and paralysis. Although accepted radiation tolerance limits for the spinal cord have successfully limited the incidence of this problem (45-50 Gy, in daily 1.8-2 Gy fractions), aggressive systemic therapy may render patients more susceptible to radiation-related neurotoxicity. We describe the case of a 38-year-old man with refractory non-Hodgkin's lymphoma who underwent matched sibling peripheral blood stem cell transplant following a conditioning regimen of cyclophosphamide (60 mg/kg x 2) and total body irradiation (120 cGy x 11). This was followed by delivery of 30.6 Gy involved-field radiation at 1.8 Gy/day to the mediastinum and left supraclavicular fossa for bulky residual tumor. Although maximum cumulative radiation dose to the spinal cord was less than 45 Gy, the patient subsequently developed progressive lower extremity weakness and MRI abnormalities of the spinal cord limited to the radiation field. This represents the second report in the literature of this unexpected complication, prompting a need to re-examine current guidelines for radiotherapy in the context of high-dose systemic treatment.- - - - - - - - - - ranking = 2keywords = spinal (Clic here for more details about this article) |
