Bladder dysfunction in acute transverse myelitis: magnetic resonance imaging and neurophysiological and urodynamic correlations.

AIMS: To evaluate micturition abnormalities in acute transverse myelitis and correlate these with evoked potentials, magnetic resonance imaging (MRI), and urodynamic findings. SETTING: Tertiary care teaching hospital. PATIENTS: 18 patients with acute transverse myelitis, aged 4-50 years; 15 had paraparesis and three quadriparesis. METHODS: Patients with acute transverse myelitis had a neurological evaluation and tibial somatosensory and motor evoked potential studies in the lower limbs. Spinal MRI was carried out using a 1.5 T scanner. Urodynamic studies were done using Dantec UD 5500 equipment. Neurological outcome was determined on the basis of Barthel index score at six months as poor, partial, or complete. In some patients, urodynamic studies were repeated at six and 12 months. RESULTS: Spinal MRI in 14 of the 18 patients revealed T2 hyperintense signal changes extending for at least three spinal segments in 13; one patient had normal MRI. In the acute stage, 17 patients had a history of urinary retention and one had urge incontinence. On follow up at six months two patients regained normal voiding, retention persisted in six, and storage symptoms developed in 10, of whom five also had emptying difficulties. Urodynamic studies showed an areflexic or hypocontractile bladder in 10, detrusor hyperreflexia with poor compliance in two, and detrusor sphincter dyssynergia in three. Early abnormal urodynamic findings commonly persisted at the six and 12 months examinations. Persistent abnormalities included detrusor hyperreflexia, dyssynergia, and areflexic bladder. The urodynamic abnormalities correlated with muscle tone and reflex changes but not with sensory or motor evoked potentials, muscle power, MRI signal changes, sensory level, or six months outcome. CONCLUSIONS: Bladder dysfunction is common in acute transverse myelitis and may be the only sequel. Urodynamic study is helpful in evaluating the bladder dysfunction and also in its management.

Herpes simplex virus myelitis: clinical manifestations and diagnosis by the polymerase chain reaction method.

Herpes simplex virus (HSV) myelitis has previously been reported to be a form of acute ascending necrotizing myelitis caused by HSV type 2 (HSV-2). We studied neurological symptoms, clinical course, magnetic resonance imaging (MRI) findings, and diagnosis by polymerase chain reaction (PCR) methods in 9 patients with HSV myelitis. In 6 cases, disease onset was marked by sensorimotor disturbances of lower extremities and urinary disturbances, with the transverse myelopathy gradually ascending to the cervicothoracic spinal cord level. The other 3 cases showed transverse myelopathy without an ascending pattern. Six cases showed acute progression, while 3 cases showed a subacute course. There were 2 cases with recurrent episodes. Three patients recovered, however, in the remaining 6 patients severe sequelae such as paraplegia persisted despite antiviral therapy. MRI showed a hyperintense lesion on T2-weighted images. Gadolinium enhancement was observed in 2 cases, and 1 case showed a hyperintense lesion both on T1- and on T2-weighted images, suggesting hemorrhagic necrosis. HSV-2 was detected by PCR techniques in all 6 cases with an ascending pattern. HSV-1 DNA was detected in 2 and HSV-2 DNA in 1 of the 3 cases with a nonascending pattern. Our findings demonstrate diverse clinical manifestations of HSV myelitis.

Transverse myelitis as a first manifestation of systemic lupus erythematosus: a case report.

Transverse myelitis as a first manifestation of systemic lupus erythematosus (SLE) is very uncommon. No pathognomonic clinical or biochemical characteristics exist, and therefore an early diagnosis is often difficult. Therapy with intravenous pulses of methylprednisolone and cyclophosphamide has been shown to improve the prognosis. However, morbidity and mortality rates in transverse myelitis are still high due to the fact that complications such as opportunistic infections and pulmonary embolism are still frequent causes of death. We report a woman with relapsing transverse myelitis which was the first manifestation of SLE. A good response to pulse methylprednisolone and cyclophosphamide therapy was obtained but she died later as a result of a pulmonary embolism. We conclude that intravenous pulse methylprednisolone and cyclophosphamide therapy improve the prognosis of transverse myelitis associated with SLE but that a careful follow-up is needed to avoid complications due to the illness itself or secondary to the therapy.

Longitudinal myelitis associated with systemic lupus erythematosus: clinical features and magnetic resonance imaging of six cases.

Myelopathy is a rare central nervous system (CNS) complication associated with systemic lupus erythematosus (SLE). Acute transverse myelitis (ATM) is the most frequent form of SLE-related myelopathy. Magnetic resonance imaging (MRI) typically shows increased signal intensity in T2-weighted images and cord swelling. In the present paper, we describe six cases of SLE-related myelopathy with multiple increased signals in the T2-weighted images involving continuous levels of the cervical and thoracic spinal cord, a distinctive feature recently named 'longitudinal myelitis'. The clinical and laboratory findings are similar to those presented by ATM patients, including paraparesis, sensory level and sphincter disturbances. Four patients had positive antiphospholipid antibodies (aPL) suggesting that this could be a characteristic of longitudinal myelitis. Treatment in all cases included high doses of corticosteroids and immunosuppressive agents (intravenous (i.v.) cyclophosphamide). Anticoagulation therapy was given to one patient and two others received low doses of aspirin. The outcome was mainly unfavorable with slow improvement in only one case, no improvement in two and relapse of the myelopathy in the remaining three. In conclusion, longitudinal myelitis is an unusual form of SLE-related myelopathy, it might be associated with aPL and it has a poor prognosis.

Acute partial transverse myelitis with normal cerebral magnetic resonance imaging: transition rate to clinically definite multiple sclerosis.

OBJECTIVE: To determine the long-term risk of developing clinically definite multiple sclerosis (CDMS) in patients with acute partial transverse myelitis (APTM) and normal cerebral magnetic resonance imaging (MRI) scans. METHODS: We retrospectively studied 30 consecutive patients with clinical evidence of APTM. Patients with symmetric severe acute transverse myelitis were considered to have complete transverse myelitis and were excluded. All patients underwent spinal and cerebral MRIs, 13 underwent cerebrospinal fluid analysis and 11 patients underwent evoked potential studies. Various other studies were performed to assess for connective tissue disease and causes of APTM other than demyelinating disease. RESULTS: After an average follow-up of 61 months, all laboratory and clinical evidence, including relapse history, indicated that three patients developed lesions on cerebral MRI and could be classified as CDMS by either Poser criteria (two patients) or MacDonald criteria (one patient). Relapses limited to the spinal cord seen clinically were seen in 14/30 (46.6%) patients. Oligoclonal bands were seen in 8/13 (62%) patients; one patient transitioned to CDMS. Unifocal lesions of the cord were seen in 19/30 (63%) patients, multifocal lesions were seen in 8/30 (27%) and 3/30 (10%) had negative MRIs. The three patients who converted to CDMS did so within five years of the onset of myelitis. CONCLUSION: APTM with normal cerebral MRI had a low rate of conversion to CDMS in this long-term study. To date, there have been only a few follow-up studies that have addressed this issue.

Idiopathic acute transverse myelitis: a clinical study and prognostic markers in 45 cases.

OBJECTIVE: The Transverse Myelitis Consortium Working Group has proposed new diagnostic criteria for idiopathic acute transverse myelitis (ATM). We reviewed patients admitted to our center diagnosed with myelitis with two objectives: (i) to evaluate the usefulness of these criteria in distinguishing between myelitis as the first episode of multiple sclerosis (MS) and idiopathic ATM; and (ii) to analyse the clinical and laboratory variables that may be used as functional prognostic markers. METHODS: We selected patients who met the criteria. We recorded clinical epidemiological data, patients treated with methylprednisolone, maximal disability reached and disability at final follow-up. We also recorded cerebrospinal fluid (CSF) data and the number of levels affected in the spinal magnetic resonance imaging (MRI). RESULTS: Twenty-four patients fulfilled the criteria for definite ATM and 21 for possible ATM. Five patients converted to MS. Mean follow-up time was 3.5 years. There was an association between younger patients and female patients with conversion to MS. The highest Rankin score reached and increased CSF glucose levels were associated with a poor outcome. In multivariate analysis, only the admission Rankin score was associated with outcome. CONCLUSIONS: (i) About 10% of patients who met the criteria may convert to MS; and (ii) admission Rankin score was the only independent prognostic factor found.

Transverse myelitis and chronic urticaria in systemic lupus erythematosus. Case report.

We report a 40 years old woman with chronic urticaria and acute transverse myelitis associated with systemic lupus erythematosus. The urticaria appeared in her adolescence and after 26 years was followed by photosensitivity, peripheral polyarthritis and acute transverse myelitis, with positive antiphospholipid and antinuclear antibodies. Both chronic urticaria and acute transverse myelitis have been described associated with or appearing as the first manifestation of systemic lupus erythematosus. Transverse myelitis is a rare and still poorly understood condition reported in about 2% of patients with systemic lupus.

[Acute transverse myelitis in systemic lupus erythematosus].

Acute transverse myelitis as complication of systemic lupus erythematosus is a known and well-characterized although uncommon clinical entity. We report here four cases of lupic myelitis collected at our hospital in the last few years and review the available literature of the last ten years, approximately the time when NMR became generally available. The clinical picture can be very variable and therefore, when facing a picture of acute myelitis, lupus should be included in the differential diagnosis; biochemistry evaluating the lupus "activity" is of poor diagnostic value, nuclear magnetic resonance is not conclusive for the etiologic diagnosis of myelitis and its prognosis has improved with therapy including pulses of steroid and immunosuppressant agents.

[DPB 1 *0501-associated opticomyelitis and atopic myelitis: novel disease entities].

To clarify the relationship between Th 1/Th 2 balance and clinical features, we studied the intracellular IFN gamma-positive versus IL-4-positive cell ratio in peripheral blood CD 4 T cells by flow cytometry and measured total and allergen-specific IgE by ELISA in 227 patients with various neurologic diseases including multiple sclerosis (MS), myelitis and HAM/TSP, and 42 healthy hospital subjects. The intracellular IFN gamma/IL-4 ratio in the patients with acute myelitis was significantly decreased, and the total serum IgE level and frequency of mite antigen-specific IgE were significantly elevated as compared with the controls. Patients with HAM/TSP, however, had a significantly higher intracellular IFN gamma/IL-4 ratio, lower total IgE level, and lower frequency of cedar pollen-specific IgE than did the controls. The patients with recurrent opticomyelitis (ROM) had a significantly higher frequency of relapse, higher EDSS score, and lower number of brain MRI lesions than the patients with conventional MS, and only those with ROM showed a significant association with the HLA-DPB 1 *0501 allele. The ROM patients had a significantly higher intracellular IFN gamma/IL-4 ratio and IL-4-/IFN-gamma + cell percentages than the controls. These findings suggest that the Th 2 cell response predominates in acute myelitis with hyperIgEaemia (atopic myelitis), whereas the Th 1 cell response predominates in ROM and HAM/TSP.

[A case report of post-rubella myelitis in an adult].

Neurological complications following rubella are only rarely encountered. We report a case of isolated myelitis. A 44-year-old healthy female suffered from an erythematous macular rash which rapidly cleared. However, the following days, dysuria initiated hospitalization. On admission, she was febrile but alert and in normal mental status. General physical examination was quite unremarkable. Four days later, she suffered from acute urinary retention, fecal retention and vaginal hypoesthesia. Routine laboratory data, chest skull and spinal column X-rays were unremarkable. The sterile cerebrospinal fluid contained 30 lymphocytes/mm3, 0.48 g/ml of protein but normal amount of glucose. Rubella antibody titers showed a significant elevation and specific IgM were detected by immunocapture. Improvement was rapid and recovery was uneventful except a mild vaginal hypoesthesia that persisted 5 weeks later. Diffuse myelitis occurring shortly after rubella vaccination have also been described. The immunopathological mechanisms by which involvement of the nervous system occurs is far from clear. Little is known about the pathogenesis of post-vaccination myelitis and although the mecanism of sensitization and the specific neural antigens are not known, post-infectious and post-vaccinal myelitis are thought to share a common pathogenic basis.

[Acute transverse myelitis secondary to hepatitis B vaccination].

INTRODUCTION: Acute transverse myelitis is an inflammatory disorder. The pathogenesis is unclear, but the probable mechanism involves an autoimmune phenomenon. Possible causes included multiple sclerosis and parainfectious and postvaccinal events. Myelitis has rarely been reported secondary to vaccinations including hepatitis B. We present a case of acute myelitis, which seems secondary to the administration of the hepatitis B vaccine. CLINICAL CASE: A 15-years-old female presented with progressive numbness of the right arm and leg, with right leg weakness. Symptom began one week after receiving the first dose of the hepatitis B vaccine. Spinal cord magnetic resonance (MR) revealed a diffuse increased signal extending from C6 to D2. Cerebral MR and cerebrospinal fluid were normal. She was treated with high doses of methylprednisolone with a complete recovery of neurological functional. Repeat medullar cord MR was normal. There was no relapse during a four years follow up. CONCLUSIONS: Potential causal relationship between vaccination against hepatitis B and multiple sclerosis was brought to the attention and to public debate. However, no conclusive association could be made between vaccination and demyelination. In the clinical setting, the distinction between a first episode of multiple sclerosis or postvaccinal myelitis depends upon subsequent course.

[Clinical features of myelitis in patients with atopic symptoms].

It is rare to see atopic symptoms in patients with multiple sclerosis(MS). However, it has been reported that in atopic patients, particularly in patients with atopic dermatitis, a benign myelitis occasionally occurs. In the present report, three atopic patients with myelitis were studied clinically and neuroradiologically. All the patients were adult men(Case 1, 2, and 3 were 41-year-old, 31-year-old, and 34-year-old, respectively), and all of them had bronchial asthma without histories of atopic dermatitis. Their manifestations were not severe and were only numbness of upper and/or lower extremities. There was no motor weakness, ataxia, or urinary incontinence. MRI studies revealed a T2-high intensity lesion in the high cervical spinal cord in the two patients(Case 2 and 3) and a T2-high intensity lesion in the lumber spinal cord in the remaining patient(Case 1). Their clinical courses were essentially all benign and well responsive to steroid therapy. Although myelitis of these patients may be a first attack of MS, their findings appear to support a recently emerging concept of the atopic myelitis.

[Acute transverse myelitis associated with ECHO-25 virus infection].

A case of acute transverse myelitis associated with ECHO-25 virus infection was reported here with a brief review of the literature. The patient was a 42-year-old house wife. Without any antecedent symptoms, weakness and paresthesia of bilateral lower extremities, and sphincter disturbance developed suddenly. Neurological examination revealed paraplegia of both legs, hyperreflexia of lower extremities, bilateral positive Babinski sign and impairment of all sensory modalities below Th4 level. No abnormality was found in myelography and CT myelography. Abnormal intensity area was found in lower cervical spinal cord on MRI. Serum antibody titer to ECHO-25 virus was elevated in the convalescent stage (X4096), and 7 month later from the onset of neurological symptoms, high value was continued (X128). We diagnosed her illness as acute transverse myelitis complicating ECHO-25 virus infection. In the literature, only 3 cases of transverse myelitis following ECHO virus infection (type 2, 5, 19) were found. This case seemed to be the first case of transverse myelitis associated with ECHO-25 virus infection.

Idiopathic transverse myelitis: MR characteristics.

PURPOSE: To describe the MR characteristics that can distinguish idiopathic transverse myelitis from other intramedullary lesions. METHODS: A total of 32 initial and follow-up MR studies in 17 patients with clinically proved transverse myelitis were reviewed retrospectively. The location, size, pattern, and segmental length of areas of hyperintensity were estimated on T2-weighted axial and sagittal images. In 15 of the patients, whose neurologic abnormalities were limited to the spinal cord, the location and pattern of intramedullary contrast enhancement were evaluated on sagittal and axial T1-weighted images. Follow-up MR studies were available for 10 patients. The statistical significance of cord enhancement between the groups with and without cord expansion was calculated. RESULTS: Common MR findings of idiopathic transverse myelitis included a centrally located hyperintensity occupying more than two thirds of the cross-sectional area of the cord (88%); a length of 3 to 4 vertebral segments (53%), with variable presence of cord expansion (47%); a small central area of intensity, isointense with normal cord, in the core of hyperintensity (47%); focal, peripheral cord enhancement (53%), particularly in patients with cord expansion; and a slow regression of T2 hyperintensity with an enhancing nodule. Although no linear correspondence was observed between MR findings and neurologic signs and symptoms, all but 4 patients improved clinically as MR findings improved or remained stable. CONCLUSIONS: MR findings are helpful in detecting transverse myelitis and in differentiating this entity from multiple sclerosis and cord tumors, but clinical assessment and observation of MR changes over time are essential in making the diagnosis.

Herpes zoster myelitis occurring during treatment for systemic lupus erythematosus.

A woman with systemic lupus erythematosus (SLE) presented with a zoster eruption. Transverse myelitis developed at the site of the dermatomal distribution of the rash. SLE and varicella zoster virus (VZV) can both cause myelitis, and are difficult to differentiate. The topographic association between the cutaneous and the neurological involvement suggesting VZV myelitis was confirmed by polymerase chain reaction (PCR) for VZV in the cerebrospinal fluid. This case illustrates the potential role of the selective amplification of VZV DNA in cerebrospinal fluid to diagnose central neurological complications associated with VZV. The value of magnetic resonance imaging of the spinal cord in the evaluation of patients with myelitis is emphasized.

Chronic recurrent transverse myelitis or multiple sclerosis.

The simultaneous occurrence of multiple sclerosis and transverse myelitis is known in the literature. Apart from the spinal symptoms, other neurological signs of brain involvement are usually found and magnetic resonance imaging (MRI) reveals disseminated foci in the brain. The positive evoked responses, the immunological abnormalities of the cerebrospinal fluid (CSF), and the oligoclonality together prove the presence of multiple sclerosis. In these cases the symptoms of transverse myelitis can separately precede other signs of multiple sclerosis, or appear as a relapse. Recurrent transverse myelitis as an independent entity, with negative MRI and CSF immunology, is an exciting topic in terms of the etiological factors and therapeutic considerations. The view in the literature is that the occurrence of transverse myelitis as an independent entity is rather rare. The present article reports the case of a female patient with recurrent spinal cord signs, and negative MRI and CSF immunology. During a ten-year follow-up observation period, symptoms of multiple sclerosis did not develop. Further studies of such cases are needed in order to clarify the etiological factors, the pathomechanism and the therapeutic considerations relating to this relatively new and probably independent clinical entity.

Acute transverse myelitis in systemic lupus erythematosus: a case of rapid diagnosis and complete recovery.

Acute transverse myelitis is a rare and serious complication of systemic lupus erythematosus. Delay in diagnosis and treatment is associated with significant morbidity and mortality. Earlier diagnosis is facilitated by magnetic resonance imaging. Treatment of systemic lupus erythematosus-related acute transverse myelitis remains controversial. The use of steroids alone may result in incomplete recovery. We report a patient who was promptly diagnosed with systemic lupus erythematosus-related acute transverse myelitis by magnetic resonance imaging. The patient had complete resolution of her symptoms following aggressive treatment with steroids and cyclophosphamide. Review of published treatment of systemic lupus erythematosus-related acute transverse myelitis suggests aggressive therapy with steroids and cyclophosphamide may provide the best outcome.

Benzene poisoning as a possible cause of transverse myelitis.

A case of transverse myelitis in a 25-year-old patient was described. The transverse myelitis was caused by toxic cause, probably as a result of benzene poisoning. This diagnosis was based on: The differential diagnosis. The patient's occupation. The abnormal high urinary phenol levels. The coincidence of decreasing urinary phenol values with an amelioration of the clinical condition of patient. After consulting the literature, we think that this case of transverse myelitis based on a benzene poisoning is the first ever described.
