摘　　要：目的:探讨儿童广州管圆线虫病的临床特征及影像表现。方法:对临床确诊的3例广州管圆线虫病患儿的临床及影像资料进行回顾性分析。结果:3例均有明确的螺类或蜗牛接触史,脑脊液及血常规示嗜酸性粒细胞升高。头颅MRI均表现为软脑膜线状和结节状强化灶,其中2例在脑实质内出现不强化结节状病灶,病灶直径0.5~2.0 cm。3例肺部CT均表现为胸膜下大小不等的实性结节影,且周围伴磨玻璃影,结节增强扫描无强化。结节分布以双肺下叶为主,但各叶均见受累。结论:线状和结节状的软脑膜强化灶、胸膜下结节伴周围磨玻璃影等是广州管圆线虫病的典型影像学表现,结合传染源接触史及嗜酸性粒细胞升高,可帮助临床医师对该病进行早期诊断。Objective:To explore the clinical features and imaging manifestations of angiostrongylus cantonensis in children.Methods:The clinical and imaging data of 3 children with angiostrongylus cantonensis diagnosed clinically were retrospectively analyzed.Results:The 3 children with angiostrongylus cantonensis had a clear history of exposure to snails.The cerebrospinal fluid and blood tests indicated an increase in the percentage of eosinophils.The head MRI of 3 patients showed linear and nodular enhancement of the leptomeningeal.Among them,2 cases developed non-enhancing nodular lesions in the brain parenchyma,with lesions ranging from 0.5 to 2.0 cm in diameter.Lung CT of three cases showed solid subpleural nodules of varying sizes with ground glass shadows around the nodules and no enhancement.The nodules were mainly distributed in the lower lobes of the lungs,but all lobes were affected.Conclusion:Combined with the typical imaging findings such as linear and nodular enhancement of lepto meningeal,subpleural nodules with surrounding ground glass shadows,as well as the history of exposure to the source of infection and the laboratory examination results of elevated eosinophils,can help early diagnosis of angiostrongylus cantonensis.
