RESUMEN
Echinococcosis is mainly prevalent in the agricultural and pastoral areas in the northwest of China, but it is relatively rare in Hunan Province. Here, we reported the clinical data of a case of echinococcosis in Hunan Province. The patient was an 11-year-old male, who sought treatment at the Second Xiangya Hospital of Central South University due to abdominal mass. According to the symptoms, signs, and laboratory examinations, he was initially diagnosed as "intra-abdominal mass" and "spleen cyst". Subsequently, he underwent abdominal massive occupying resection and splenectomy. Postoperative pathological examination revealed the cuticle and germinal layer of hydatid and protoscolex, which was consistent with characteristics of echinococcosis. In addition, the serological examination showed that the specific anti-hydatid IgG antibody was positive. Combined with the patient's condition, he was given praziquantel treatment. After a month of follow-up, the patient was asymptomatic.
