摘要/Abstract

摘要：

13岁男性患儿因“食欲下降伴体质量不增半年余”，2025年7月1日就诊于江苏省血吸虫病防治研究所附属门诊部。多次查CT示肺部炎症，病灶呈游走性。血常规提示嗜酸粒细胞计数和百分比增加。血清学检测结果示多种寄生虫抗体阳性。使用改良加藤厚涂片法进行粪检，镜下可见纺锤形鞭虫虫卵。患儿为云南毕节人，有饮生水、生食史。结合患儿流行病学史、临床表现和相关检验结果，诊断为鞭虫感染引起的游走性肺炎。予患儿阿苯达唑（口服，200 mg/次，2次/d，连服3 d）治疗。服药后1周复查，血常规示嗜酸粒细胞下降，胸部CT示肺部炎症消退，粪检虫卵转阴。服药后2周患儿食欲明显改善，无其余不适。

Abstract:

A 13-year-old male patient was admitted to the Outpatient Department of Jiangsu Institute of Parasitic Diseases on July 1, 2025, due to decreased appetite with no weight gain for more than half a year. Repeated CT scans showed pulmonary inflammation and migratory lesions. Routine blood tests showed an increased eosinophil count and percentage, and serological tests indicated positive antibodies against multiple parasites. Modified Kato-Katz thick smear technique of stool samples displayed spindle-shaped Trichuris trichiura eggs under a microscope. The case resided in Bijie, Yunnan Province, and had a history of consuming raw water and food. Migratory pneumonia caused by T. trichiura infection was diagnosed based on the patient’s epidemiological history, clinical manifestations and laboratory findings. The case was given albendazole by oral gavage (a single dose of 200 mg, twice daily for 3 consecutive days). Blood routine tests one week post-treatment showed a decrease in eosinophils, and chest CT scans displayed alleviated pulmonary inflammation, with no parasite eggs identified in stool samples. The patient’s appetite improved remarkably with no other discomfort 2 weeks post-treatment.
