          Abstract

          Abdominal angiostrongyliasis is a parasitic disease caused by Angiostrongylus costaricensis, a metastrongylid nematode with wide geographic distribution, occurring from the United States to Argentina. In Brazil, the disease has been reported from the States of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Federal District of Brasilia and Minas Gerais. We report here a case of abdominal angiostrongyliasis in a 9-year-old girl, from Itatiba, State of Espirito Santo, Brazil, submitted to exploratory laparotomy for acute abdomen. Extensive inflammatory lesions of terminal ileum and cecum, with perforations of the first, were present, and ileocecal resection was performed. The pathological picture was characterized by transmural inflammatory granulomatous reaction, extensive eosinophilic infiltration, eosinophilic vasculitis and the presence of worms within a mesenteric artery branch, with histological features of metastrongylid nematodes. This case report contributes to a better knowledge of the geographic distribution of this parasite in Brazil, suggesting that abdominal angiostrongyliasis may represent a disease of medical importance, more than a rarity of academic interest.

          Angiostrongylus costaricensis, um parasita nematódeo, com ampla distribuição geográfica, é o agente causal da angiostrongilíase abdominal. No Brasil, a doença tem sido descrita nos Estados do Rio Grande do Sul, Santa Catarina, Paraná, São Paulo e Minas Gerais e no Distrito Federal. Relatamos a ocorrência de um caso de angiostrongilíase abdominal no estado do Espírito Santo, Brasil. Paciente de 9 anos de idade, sexo feminino, foi submetida a laparotomia exploradora por abdômen agudo. Foram observadas lesões inflamatórias extensas de íleo terminal e ceco, com perfuração do íleo, tendo sido realizada ressecção do segmento acometido. O estudo anatomopatológico mostrou inflamação granulomatosa transmural, infiltrado intenso de eosinófilos, vasculite eosinofílica e a presença de parasitas, com características histológicas de nematódeos metastrongilídeos no interior de ramo da artéria mesentérica. Nosso relato contribui para uma melhor definição da distribuição geográfica desse parasito no Brasil, evidenciando assim a importância médica dessa parasitose, anteriormente considerada como uma raridade de interesse apenas acadêmico.

            Angiostrongylus costaricensis n. sp. (Nematoda: Metastrongyloidea), a new lungworm occurring in man in Costa Rica

            Angiostrongylus costaricensis n. sp. is described from Costa Rica where it produces lesions in the abdominal cavity of man. It can be distinguished from other species of the genus on the basis of its size, the length of the spicules, the position of the vulva and the morphology and position of the bursal rays. The parasite localizes in the small mesenteric arteries, especially in the ileocecal region, where it produces arteritis and thrombosis. Eggs in various stages of embryonation were found scattered in the tissues of the intestinal wall and regional lymph nodes, eliciting a granulomatous inflammatory reaction with in. tense eosinophilic infiltration

              On the diversity of mollusc intermediate hosts of Angiostrongylus costaricensis Morera & Cespedes, 1971 in southern Brazil

              Veronicellid slugs are considered the most important intermediate hosts of Angiostrongylus costaricensis, an intra-arterial nematode of rodents. Studies undertaken in three localities in southern Brazil led to identification of molluscs other than veronicellid slugs as hosts of A. costaricensis: Limax maximus, Limax flavus and Bradybaena similaris. These data indicate a low host specificity of larval stages of A. costaricensis, as it has been reported to other congeneric species.
