“…Lumbago was described in 12 (92.3%) of the cases, and this was in accordance with the literature consulted, that described this symptom from 72.2% up to100% of the patients 3,4,10,12,14,15 . The classical triad of complaints (lumbago, urinary dysfunction and paresthesias in lower limbs), was identified in 11 (84.61%) patients in the present study.…”

In neuroschistosomiasis, the spinal cord is the most common place of the disease. In high prevalent areas for schistosomiasis mansoni, the clinical alertness is important for an early diagnostic, in order to decrease the final neurological damage. This study provides some useful neurologic information about a series of patients with schistosomal myelitis. Method: The sample consisted of 13 schistosomiasis mansoni carriers examined at the moment of the diagnosis of myelitis. Results: The classical triad (lumbago, weakness at the lower limbs and urinary dysfunctions) was documented in 11 (86.61%) patients. The distribution of the clinical forms was: myeloradicular in six patients (46.15%), radicular in four (30.76%) and myelitic in three (23.07%). Conclusion: The radicular dysfunction and their clinical associated forms were the most prominent pattern during the early phase of this disease. Key words: schistosomiasis mansoni, neuroschistosomiasis, myelitis, neurologic exami nation, medical history taking.Preponderância de disfunções radiculares na avaliação clínica precoce da mielite pelo Schistosoma mansoni RESUMO Na neuroesquistossomose, a medula espinhal é o sítio de predileção da doença. Em áreas de alta prevalência para esquistossomose mansoni, o conhecimento clínico dessa condição é importante para o seu diagnóstico precoce e consequente redução da lesão neurológica definitiva. Este estudo provê informações neurológicas relevantes pertinentes a uma série clínica de pacientes com mielite esquistossomótica. Método: A amostra consistiu de 13 pacientes portadores de esquistossomose mansoni examinados no momento do diagnóstico de sua forma mielítica. Resultados: A tríade clássica (lombalgia, fraqueza nos membros inferiores e disfunções urinárias) foi documentada em 11 (86,61%) pacientes. Quanto à distribuição das formas clínicas, se observou a ocorrência da mieloradicular em seis pacientes (46,15%), da radicular em quatro (30,76%) pacientes e da mielítica em três (23,07%) pacientes. Conclusão: A disfunção radicular e suas formas clínicas associadas foram o padrão mais frequente durante a avaliação na fase precoce da doença.

Schistosomiasis is a serious public health problem in some regions of the world. It is endemic in more than 74 countries and accounts for the majority of the cases of portal hypertension among the young population in these areas. Around the world, it is believed that there are about 200 million people infected by the Schistosoma species S. mansoni, S. haematobium, S. japonicum, S. intercalatum and S. mekongi 1,2 .The temporal clinical and systemic forms of the disease are: acute (toxemic and non-toxemic), latent and chronic 2,3 . The latter is divided into mild forms (intestinal and hepaticintestinal) and severe forms (hepatosplenic, pulmonary and glomerular) 2,3 .The presence and clinical significance of neurological lesions depend on the combination of the presence of eggs in the nervous system and the immune response of the host. In the majority of cases, a type IV or granulomatous delayed immune response occurs, and the response is greater in the earlier phases of schistosomiasis. In chronic forms, it becomes localized and attenuated (immunological modulation phenomenon) 4,5 . ABSTRACTThe diagnosis of schistosomal myelitis (SM) is frequently presumptive because no findings from any complementary examination are pathognomonic for this disease. The present report describes some abnormalities seen on magnetic resonance imaging (MRI) evaluation of a series of SM patients and discusses their etiopathogenesis. Methods: This study evaluated SM patients at the time of their diagnosis. These patients routinely underwent MRI on all segments of the spinal cord. Results: Thirteen patients were evaluated. The MRI was abnormal in 12 (92.3%) of them. In 11 patients (84.61%), the damage reached two or more spinal segments. Conclusions: MRI was an important diagnostic aid in this sample, because of the high rate of abnormalities detected. The tissue damage observed on MRI was extensive in the majority of the patients.Key words: Schistosoma mansoni, neuroschistosomiasis, myelitis, magnetic resonance imaging, diagnosis. RESUMOO diagnóstico da mielite esquistossomótica é frequentemente realizado por presunção, não havendo achado de exame complementar que seja patognomônico à condição. O presente estudo descreve alterações presentes na avaliação desses pacientes pela técnica da ressonân-cia magnética e discute sua etiopatogênese. Métodos: O estudo avaliou pacientes com mielite esquistossomótica no momento do diagnós-tico, os quais foram submetidos, rotineiramente, à ressonância magnética de todos os segmentos medulares. Resultados: Foram avaliados 13 pacientes, sendo a ressonância magnética alterada em 92.3% dos casos. Em 11 pacientes (84.61%), o dano abrangeu dois ou mais segmentos espinais. Conclusões: A ressonância magnética espinhal foi um importante auxílio diagnóstico nessa casuística em virtude da alta taxa de alterações detectadas. O dano tecidual observado foi extenso na maioria dos pacientes.Palavras-Chave: Schistosoma mansoni, neuroesquistossomose, mielite, imagem por ressonância magnética, diagnóstico.

“…9 It is essential for cutaneous schistosomiasis to be included in the list of differential diagnosis of skin lesions, mainly in endemic areas, since a late diagnosis and, consequently, delay in establishing adequate treatment may bring disastrous consequences for the patient, as cases have been reported where skin lesions preceded the onset of medullary lesions (neuroschistosomiasis), with sequelae like paresis and paraplegia. 10 At present, the medications available for treatment of Schistosomiasis mansoni are oxamniquine and praziquantel. These two drugs are equivalent regarding efficacy and safety.…”

Schistosomiasis mansoni is a systemic disease caused by a helminth of the schistosoma genus. The disease is generally asymptomatic or gastrointestinal symptoms may predominate. Skin lesions related to the disease are rarely diagnosed, even in endemic areas. The authors report the case of a young girl diagnosed with cutaneous schistosomiasis with involvement of the abdomen, back and scapular region. Schistosoma eggs were found in the lesions by histopathologic exam. There was no evidence of systemic involvement. Schistosomiasis must be included in the list of differential diagnosis of skin damage, especially in endemic areas, due to the potential consequences, in case of late diagnosis and treatment.
