Simultaneous occurrence of brain tumor and myeloradiculopathy in schistosomiasis mansoni: case report.

Simultaneous occurrence of brain tumor and myeloradiculopathy in cases of Manson's schistosomiasis have only rarely been described. We report the case of a 38-year-old man who developed seizures during a trip to Puerto Rico and in whom a brain tumor was diagnosed by magnetic resonance imaging: brain biopsy revealed the diagnosis of schistosomiasis. He was transferred to a hospital in the United States and, during hospitalization, he developed sudden paraplegia. The diagnosis of myeloradiculopathy was confirmed at that time. He was administered praziquantel and steroids. The brain tumor disappeared, but the patient was left with paraplegia and fecal and urinary dysfunction. He has now been followed up in Brazil for one year, and his clinical state, imaging examinations and laboratory tests are presented here.

Tem sido descrita, raramente, na esquistossomose mansônica, a ocorrência simultânea de tumor cerebral e mielorradiculopatia. Relatamos aqui o caso de um homem de 38 anos que desenvolveu convulsões, durante viagem a Porto Rico, e um tumor cerebral foi diagnosticado à ressonância magnética: a biópsia do cérebro revelou o diagnóstico de esquistossomose. Ele foi transferido para hospital na América do Norte e durante a hospitalização desenvolveu súbita paraplegia. O diagnóstico de mielorradiculopatia foi confirmado na ocasião. Ele recebeu praziquantel e esteróides. O tumor cerebral desapareceu, mas o paciente permaneceu com paraplegia, disfunção urinária e fecal. Ele tem sido acompanhado no Brasil no último ano e o seu estado clínico, os métodos de imagem e os exames de laboratório são apresentados aqui.

Sparganosis presenting as radiculalgia at the conus medullaris.

A 26-year-old female presented with severe lumbodorsal pain and hypesthesia in the right lower extremity. MRI of the spine revealed multiple lesions from L1 to S5; the largest was located at the conus medullaris. Diagnostic exploration revealed caseous, ivory-colored granulation tissue adhered to the conus medullaris and cauda eguina. Results of enzyme-linked immunosorbent assay and histopathological staining were consistent with sparganum infection. Our case report is unique because presentation was with lumbar radiculopathy instead of functional disorders of urination and defecation, atypical presentation for a conus medullaris lesion. Parasitic infection of the spinal cord with sparganosis should be considered when presentation is with signs and symptoms of spinal cord dysfunction of insidious onset.

Acute toxemic schistosomiasis complicated by acute flaccid paraplegia due to schistosomal myeloradiculopathy in Sudan.

A 55-year old Sudanese physician presented with one month history of diarrhea, loss of weight (10 kg) and low grade nocturnal fever. Following colonoscopy, he rapidly developed paraparesis and retention of urine. Magnetic resonance imaging (MRI) of the spinal cord showed low cord lesion suggestive of transverse myelitis. We present a detailed account of diagnostic and management challenges and a literature review of the final diagnosis of acute toxemic schistosomiasis, complicated by acute flaccid paraplegia due to schistosomal myeloradiculopathy. We are reporting this case to increase the awareness of physicians of schistosomal myeloradiculopathy, as it needs urgent specific treatment praziquantel and steroids. An early follow-up with MRI of the spinal cord (2 weeks treatment) may help in preventing unnecessary neurosurgical intervention. Bilharziasis may be contracted on the banks of the river "White Nile" in urban areas. Finally, clinicians should make use of the Google computer search for diagnosis in difficult cases.

Disseminated intraspinal hydatid disease.

Spinal echinococcosis is a rare entity, accounting for 1% of all cases of hydatid disease. The authors report the case of a 60-year-old man whom they treated for recurrent nerve root compression due to disseminated intraspinal echinococcosis (hydatid disease). Six years previously he had undergone surgery on an emergency basis at another institution after presenting with acute paraplegia due to a primary extradural hydatid cyst of the thoracic spine. Unfortunately, during surgical removal of the cysts, the echinococcosis disseminated into the spinal canal. This complication was documented by magnetic resonance (MR) imaging. In the 4 years before the authors treated him, he was hospitalized 4 times for 4 recurrences of nerve root compression. The authors treated the disseminated disease successfully with total T7-8 corpectomy, grafting with titanium cage and Texas Scottish Rite Hospital instrumentation, and long-term administration of albendazole (400 mg daily). Early diagnosis, proper utilization of MR imaging, and radical resection of diseased vertebrae and soft tissues followed by anthelmintic treatment are essential to control disseminated spinal hydatidosis and prevent recurrence.

Guidelines for the diagnosis and treatment of schistosomal myeloradiculopathy.

Schistosomal myeloradiculopathy is the most severe and disabling ectopic form of Schistosoma mansoni infection. The prevalence of SMR in centres in Brazil and Africa that specialise in attending patients with non traumatic myelopathy is around 5%. The initial signs and symptoms of the disease include lumbar and/or lower limb pain, paraparesis, urinary and intestinal dysfunctions, and impotence in men. The cerebrospinal fluid of SMR patients shows an increase in protein concentration and in the number of mononuclear cells in 90% of cases; eosinophils have been reported in 40%. The use of magnetic resonance imaging is particularly valuable in the diagnosis of Schistosomal myeloradiculopathy. The exclusion of other myelopathies and systemic diseases remains mandatory. Early diagnosis and treatment with steroids and schistosomicides provide a cure for most patients, whilst delayed treatment can result in irreversible physical disabilities or death. To improve awareness concerning Schistosomal myeloradiculopathy amongst public health professionals, and to facilitate the control of the disease, the Brazilian Ministry of Health has launched a program of education and control of this ectopic form of schistosomiasis. The present paper reviews current methods for the diagnosis of SMR and outlines protocols for treatment of the disease.

A mielorradiculopatia esquistossomótica é a forma ectópica mais grave da infecção pelo Schistosoma mansoni. A prevalência da mielorradiculopatia esquistossomótica em centros médicos no Brasil e em África, especializados no atendimento de pacientes com mielopatia, encontra-se em torno de 5 por cento. Os sintomas e sinais iniciais da doença incluem: dor lombar e/ou dor em membros inferiores, paraparesia, disfunções urinária e intestinal, e impotência no homem. A análise do líqüor destes pacientes revela aumento na concentração de proteínas e no número de células mononucleares em 90 por cento dos casos; a presença de eosinófilos foi documentada em 40 por cento. O uso rotineiro da ressonância magnética tornou-se obrigatório na definição diagnóstica. A exclusão de outras mielopatias e doenças sistêmicas é mandatória. O diagnóstico precoce e o tratamento com corticoesteróides e esquistossomicidas curam a maioria dos pacientes, enquanto o atraso em iniciar o tratamento resulta em seqüelas irreversíveis ou morte. Para melhorar a percepção da importância da mielorradiculopatia associada à esquistossomose, o Ministério da Saúde do Brasil lançou programa de controle dessa forma ectópica da esquistossomose. Nesta revisão, descrevem-se os métodos diagnósticos atuais para o diagnóstico e os protocolos para o tratamento da doença.

Morbidity of schistosomiasis mansoni in the state of Minas Gerais, Brazil

From 2002 to 2005, a program of active search for patients with hepatosplenic schistosomiasis and schistosomal myeloradiculopathy has been implemented in the state of Minas Gerais by the local Health Department. The state was divided in 28 regional health centers and the local representatives have been trained to identify and direct patients with hepatosplenic schistosomiasis and neuroschistosomiasis to a reference center in Belo Horizonte, the capital of the state of Minas Gerais. Seventy five patients with hepatosplenic schistosomiasis and 54 with schistosomal myeloradiculopathy have been referred and examined in the reference center in a period of time of 3 years. Schistosomal myeloradiculopathy should be emphasized because the number of cases reported is increasing rapidly and when timely diagnosed and treated, they respond promptly to treatment. Left untreated, they die or become invalid for life. In our view, the time has come for more active investigation of the different aspects of morbidity caused by schistosomiasis mansoni in Brazil.

Clinical-epidemiological profile of children with schistosomal myeloradiculopathy attended at the Instituto Materno-Infantil de Pernambuco

The most critical phase of exposure to schistosomal infection is the infancy, because of the more frequent contact with contaminated water and the immaturity of the immune system. One of the most severe presentations of this parasitosis is the involvement of the spinal cord, which prognosis is largely dependent on early diagnosis and treatment. Reports on this clinical form of schistosomiasis in children are rare in the literature. We present here the clinical-epidemiological profile of schistosomal myeloradiculopathy (SMR) from ten children who were admitted at the Instituto Materno-Infantil de Pernambuco over a five-year period. They were evaluated according to an investigation protocol. Most of these patients presented an acute neurological picture which included as the main clinical manifestations: sphincteral disorders, low back and lower limbs pain, paresthesia, lower limbs muscle weakness and absence of deep tendon reflex, and impairment of the gait. The diagnosis was presumptive in the majority of the cases. This study emphasizes the importance of considering the diagnosis of SMR in pediatric patients coming from endemic areas who present a low cord syndrome, in order to start the appropriate therapy and avoid future complications.

Treatment of schistosomal myeloradiculopathy with praziquantel and corticosteroids and evaluation by magnetic resonance imaging: a longitudinal study.

BACKGROUND: The best treatment for schistosomal myeloradiculopathy (SMR) remains undefined. There is also no longitudinal study to estimate the value of magnetic resonance imaging (MRI) in the diagnosis and follow-up of this disease. METHODS: Patients with the following presentation were considered for study: lumbar and/or lower limb pain; lower limb weakness; anesthesia, hypoesthesia, or paresthesia; bladder and/or intestinal dysfunction; and sexual impotence. Sixteen patients with SMR were treated with oral praziquantel (50 mg/kg in a single dose) and methylprednisolone (15 mg/kg/day intravenously for 5 days) followed by prednisone (1 mg/kg/day orally for 6 months). Clinical outcome was prospectively evaluated in months 2 and 6 of treatment. RESULTS: Image alterations were detected by MRI at diagnosis for all patients, and normalization or improvement was reported at the end of treatment. There was statistically significant clinical melioration at both the second and sixth months of therapy for most neurological alterations. However, the best clinical outcome was achieved when the steroid was given for >2 months. CONCLUSIONS: Treatment with praziquantel associated with corticosteroids was successful in all cases. MRI proved to be a good method for the diagnosis of SMR and helpful in the evaluation of response to treatment.

Spinal cord schistosomiasis: a prospective study of 63 cases emphasizing clinical and therapeutic aspects.

A prospective study was conducted on 63 patients with schistosomal myeloradiculopathy admitted to a university hospital in Brazil. They were evaluated according to a protocol and treated with corticosteroid and praziquantel. The disease, in general, presented as a lower cord syndrome of acute progression characterized by motor, sensory and autonomic dysfunctions. The severity of the clinical picture was different among the patients, but the symptoms were quite constant. Cerebrospinal fluid examination showed an inflammatory pattern with or without eosinophils and/or IgG against schistosomal antigens. The most frequent alterations detected by imaging methods were enlargement of the medullary cone and of the roots of the cauda equina. Schistosome egg counts suggested a low parasite burden in 71.6% of the cases. Outcome was favorable in 38 (60.3%) patients and improvement usually started within the first 48 h after commencing on corticoid and was faster during the early period of treatment.

Primary spinal extradural hydatid cyst in a child: case report and review of the literature.

Spinal hydatid cyst is a rare but serious condition. An 8-year-old boy presented with back pain, progressive weakness and numbness in both legs. Magnetic resonance imaging (MRI) of the lumbar region showed a cystic lesion with regular contour located in extradural space. There was cerebrospinal fluid- (CSF-) like signal intensity on T1- and T2-weighted images. The lesion had excessively compressed the dural sac and caudal roots, and expanded to the L3 and L4 neural foramina. The case was explored with L2, L3, L4 laminectomy and the hydatid cyst was removed totally. The clinical presentation, diagnosis and surgical treatment of this rare case of spinal hydatid disease is discussed, and all available cases of primary extradural hydatid cyst reported in the literature are presented.

[Toxocara canis meningoradiculitis]. / Méningo-radiculite à toxocara canis.

Various neurological pictures attributed to human toxocariasis are sparsely reported in the literature. A case of toxocaral infection presenting as meningoradiculitis is described herewith. Etiological diagnosis was oriented by the finding of an eosinophilia in the spinal fluid, then confirmed by the result of the immunodiagnosis of toxocariasis from both serum and spinal fluid.

Schistosomal myeloradiculopathy due to Schistosoma mansoni: report on 23 cases

Schistosoma mansoni infection is likely to be responsible for a significant proportion of cases of myelopathy occurring in areas where schistosomiasis is endemic. The aim of this study is to describe the clinical, laboratory and therapeutic data of 23 patients with schistosomal myeloradiculopathy. The medical records of 23 patients with schistosomal myelopathy admitted to two general hospitals of Belo Horizonte (MG), in Brazil, from 1995 to 1999, were reviewed retrospectively. Seventeen patients were male (74 percent). The mean age for the whole group was 27 years. Lower limb weakness and associated lumbar and/or lower limb pain were reported by 20 patients (87 percent), and 16 (70 percent) were unable to walk. All individuals presented urinary retention and 19 (83 percent) complained of intestinal dysfunction. The treatment was based on the association of antischistosomal drugs and corticosteroids. Five patients (22 percent) presented a full response to treatment, 13 (57 percent) partial response without functional limitations and 4 (17 percent) partial improvement with limitations or no response. Three out of the 4 patients who stopped steroids before 45 days of treatment developed recurrence of the symptoms and signs of myelopathy. Our cases demonstrate the severe presentation of the disease and the data disclosed here suggest that treatment with steroids should be kept for months after clinical improvement

[Angiostrongylosis in infants in Reunion and Mayotte. Apropos of 3 cases of eosinophilic meningitis including 1 fatal radiculo-myeloencephalitis with hydrocephalus]. / L'angiostrongylose chez le nourrisson à la Réunion et à Mayotte. A propos de trois méningites à eosinophiles dont une radiculomyéloencéphalite fatale avec hydrocéphalie.

BACKGROUND: Eosinophilic meningitis caused by Angiostrongylus cantonensis is widespread in Southeast Asia and Pacific islands. Adults develop a transient meningitis with a benign course but severe or fatal disease may occur in pediatric patients. CASE REPORT: Case 1. A 11-month-old boy living in Mayotte island was hospitalized a few days with fever and skin rash following by seizure, coma, flaccid quadraplegia, absence of deep tendon reflexes, urinary retention and anal incontinence. Eosinophilia was observed in peripheral blood and cerebrospinal fluid. He further developed a triventricular hydrocephalus treated by ventriculoperitoneal shunt. The child died 3 weeks later. A serodiagnosis of angiostrongylus infestation was restrospectively established. Case reports 2 and 3.-Two infants, 10 and 11-month-old-boys, living in Reunion island, developed fever and vomitings, irritability and, for one of them, unilateral sixth cranial nerve palsy. There was eosinophilia in the peripheral blood and in the cerebrospinal fluid. All symptoms progressively disappeared with complete recovery. The suspected diagnosis of angiostrongylus infestation was confirmed by the serology. CONCLUSION: We report the first case of Angiostrongylus cantonensis infection in the French island of Mayone (Comoro Islands) and we confirm the presence of this disease in Reunion island. In this Indian Ocean area, eosinophilic meningitis occurs most of the time in infants with sometimes severe radiculomyeloencephalitic forms.

[Meningoradiculitis and bilharziasis]. / Méningoradiculite et bilharziose.

A 55-year-old French man was admitted with acute retention of urine. Three days before admission he developed back pain, lower limb pain and weakness. He had last been in Nigeria 2 years previously. Schistosoma mansoni ova were identified on rectal mucosal biopsy. Our patient showed spontaneous clinical improvement. He was treated with Praziquantel and corticosteroids. The clinical manifestations of spinal schistosomiasis can be diverse, and there should be a high index of suspicion for all patients from endemic areas. Currently, praziquantel and corticosteroids are the drug of choice for Schistosoma mansoni infection.

Eosinophilic meningitis and radiculomyelitis in Thailand, caused by CNS invasion of Gnathostoma spinigerum and Angiostrongylus cantonensis.

During the 6 year period from January 1980 to December 1985 44 patients with infection of the central nervous system by Gnathostoma spinigerum or Angiostrongylus cantonensis were admitted to the Division of Neurology, Ramathibodi Hospital, Bangkok, Thailand. In 16 patients the diagnosis could be confirmed serologically by means of ELISA techniques. In gnathostomiasis encephalitis, myelitis, radiculitis and subarachnoid haemorrhage formed the majority of clinical syndromes. Intracerebral haematoma and transitory obstructive hydrocephalus are described in this report as being caused by Gnathostoma spinigerum infection for the first time. In angiostronglyus infections the clinical syndrome of meningitis was predominant, but one patient, whose angiostrongyliasis was proved serologically, also showed bilateral paresis of abducens nerve. The main laboratory finding was eosinophilic pleocytosis in the CSF (greater than 10%) which in patients originating or returning from South-East-Asia, particularly Thailand, is highly suggestive of these parasitic infections. Increasing transcontinental travel, influx of refugees and those seeking asylum as well as importation of food from South East Asian countries demand greater awareness of these parasitic infections even in Central Europe.
