A retrospective study was done to determine the presence of abdominal angiostrongyliasis in Nicaragua. Twelve cases of this parasitic disease were found among 48 visceral specimens: small intestine, liver and testes. The patients with intestinal lesions presented symptoms of an acute abdomen, and in some instances, a tumor-like mass was palpated in the lower right quadrant. A thickening of the intestinal wall accompanied by necrosis and perforation were the most important macroscopic findings. One patient with hepatic localisation of Angiostrongylus costaricencis displayed a clinical picture of visceral larva migrans-like syndrome. The chief laboratory findings were leukocytosis and eosinophilia. The histopathological examination showed granulomas and heavy eosinophilic infiltration around the eggs and larvae of A. costaricencis. Also, an adult worm was seen in one biopsy.
开展了一项回顾性研究，以确定尼加拉瓜是否存在腹部管圆线虫病。在48份内脏标本（小肠、肝脏和睾丸）中发现了12例这种寄生虫病。肠道病变患者表现出急腹症症状，在某些情况下，可在右下腹触及肿瘤样肿块。肠壁增厚伴坏死和穿孔是最重要的宏观表现。1例哥斯达黎加管圆线虫肝脏定位患者表现出内脏幼虫移行症样综合征的临床症状。主要实验室检查结果为白细胞增多和嗜酸性粒细胞增多。组织病理学检查显示，在哥斯达黎加管圆线虫的虫卵和幼虫周围有肉芽肿和大量嗜酸性粒细胞浸润。此外，在一次活检中发现了一条成虫。
